TL;DR: This is a builder's kit. I created it months ago and debated whether to rewrite the description. There's some useful stuff in here so parse it as you like or just print it and launch. Enjoy! Introducing the BetaMax Mk4 Model Rocket…
Introduction : The Extreme Series of Builders Kits were designed to print, assemble, and fly easily. These rockets can be flown on lower-powered motors in a park, or with higher-powered 24/29mm motors. Typically, an Estes F15 can loft…
Model: Model Rocket 29mm Motor Mount Tubes Overview: These are motor mount tubes for BT60, BT65, BT70, and BT80 Estes body tubes. While the stock kit MMTs work well enough, there are not many out there that are designed for 29mm motors in…
Update 6/5/2024: I have updated the Nosecone. The original appears to be an early version and while printing, it broke easily at the shoulder. The new one should work much better. I also modified the z-axis height so now it sits at…
These are Motor Mount Tube (MMT) assemblies for 18mm model rocket motors that will fit BT-50, BT-55, or BT-60 body tubes. I wanted to update my 18mm Motor Mount for BT-50 Model Rocket and decided to add the BT-55 and BT-60 as well. I…
TL;DR If you are in need of a 38mm motor retainer for your rocket, this might be a solution for you. It contains variations of centering rings and retainer options to hopefully suit your needs, or at least give you a head-start.…
Updates : 8/1/2024: Posted Mk2v1 10/13/2024: Added extended Nosecone coupler for a more secure fit Introduction: The 3-in Bullpup is an upscaled version of my Bullpup - Extreme Series rockets. It incorporates a tailcone motor retainer and…
Update: 5/11/2024: I have upgraded the nosecone for this kit, found here . If you have a printer, that is capable of printing up to 290mm, then you may wish to give that one a try. There is nothing wrong with the nosecone within the kit.…
This is the 29mm model rocket motor retainer that I designed for the Extreme series rockets. I have flown several rockets dozens of times with these using both PLA and PETG. They are straightforward to assemble and removes the need for…
Introduction: UPDATE 5/27/2024: I have added a printable body tube. This has not been tested but it should work with PETG, ASA, or ABS. The recess for the nose cone is shallower than the fincan (38.5mm vs 40.5mm), so don't get the…
Update: The maiden flight was conducted on August 17th, 2024, at the C.R.A.S.H. launch event. It was flown with an Aerotech E30-7, achieving an apogee of 1,003 ft -- seen here . ---- The Extreme Series of Builders Kits were designed to be…
UPDATE: 8/19/2024 - I added two different motor adapters, a single 24mm from SiegeCraftPB for Aerotech motors and a clamshell design for Estes D bp motors from CWBullet UPDATE: 7/18/2024 - I added a thrust ring designed for the Estes 29mm…
UPDATE: 8/21/2026: Included a one-piece nosecone per request Introducing The Malice, a downscaled replica of the fan favorite, Punisher. This rocket features three different design configurations based on months of research and…
My son lost his launch lug when building his latest rocket and asked me to print him another one. Since he wants to launch with high-power power rockets, he needs to launch off the rail (club guidelines) but he didn't want both, so I…
UPDATED: This is still a work in progress. While I am confident that the model is usable and safe, I will make changes as the design improves 3/31/2024: This was test-flown with all printed parts. It did not fair well. The fincan coupler…
There is nothing like a simple update to a model that changes everything. I love both of these models and was a little bit disappointed when I couldn't get the helping hands to work like I wanted. There is nothing wrong with the designs,…
In a previous update, there was a mixup with the cap and I posted one too big. these should all work together now. I sincerely apologize for the confusion. I initially created these for my Wildman Punisher 3 model. Recently, I've received…
Updates: 7/4/2024: Fixed a minor fitment issue with the Nosecone MID section. Now at v1.2 7/5/2024: Added a forward CR for 54mm with a cutout for 13mmx3mm tubular nylon shock cord. 7/7/2024: I flew this model on its maiden flight. See…
This is a variation of my 54mm motor retainer . It has two unique differences. First, the aft end of the cap (face) is flat, so you can print it face down. Second, the ring has a series of screw holes to attach it to a backing centering…
Introduction : The Extreme Series of Builders Kits were designed to print, assemble, and fly easily. These rockets can be flown on lower-powered motors in a park, or with higher-powered 24/29mm motors. Typically, an Estes F15 can loft…
Update: 09/12/2005 - I have added rail buttons, just in case you needed them. Update: 11/19/2025 - trimmed off 5mm from each fin so that it might fit on smaller beds. Let me know! Update: 11/21/2025 - I pulled the Stubby fincan. It didn't…
These are a couple Epoxy cups that I used while building Rockets. Using the leftover filament that lingers, I size these up in my slicer based on my need and print. Typically, I keep the brims shallow to keep from overfilling and cooking…
This is the latest iteration of my 3-in nosecone designed for use with the Estes Big Red Max or the Great Goblin kits. It can also be used for other 3-inch rockets. I designed it to print in two parts but realized that most printers do…
====================== Change Log: ====================== 12/23/2025 - By request, added a one-piece fincan. It's big and gnarly, so buckle up! 12/23/2025 - The offset for the threaded parts was a little tight, so I reduced the threaded…
The 3-in Doorknob Nosecone Ebay Upgrade! Introduction: This model is an upgrade to the Estes 3-in Doorknob and to my 3-in Doorknob Builders Kit . It includes the ring that will fit inside the shoulder of the nosecone, the ebay sled, and…
LOC/Precision 4-in Body Tube Coupler This coupler was designed specifically for the LOC/Precision 4-in (102mm) body tubes. Dimensions: 99.3mm diameter 203mm high (8 inches) 3mm thick It's a slip fit, meaning it will pass through the tube…
These are designed for larger model rockets (≥ 3-in body tube) to fit on a 1010 aluminum extrusion ("rail") with just enough wiggle room to prevent binding but will slide nicely and keep the pointy end going up. They have 6mm holes so a…
I am building a Wildman Punisher 3 high power rocket and needed a fin jig. I probably have something that will work but I found this and it's great. I put in the config and it spit out a STL file that appears to work. Everything lines up…
This post is an advanced publishing for the Rockety Forum members. You are welcome to download and enjoy the parts, but I am not supporting them unless you contact me via my build thread on TRF . When I release this model to the general…
Bride of Bar Fly: 3-Inch High Power Model Rocket Builder's Kit Change Log: 12/29/2025: Updated 1-piece Fincan with fin fillets - somehow a version without fillets made into my master model collection 12/30/2025: Updated the Nosecone Cap…
Introduction This is a nosecone and internal ebay designed to pair with IPL's PowerSlide fincan. The ebay sled also originates from IPL , but has been heavily modified to fit in this nosecone, and should be able to accommodate most…
Update: 7/21/2023 - I flew my SpiderMax that is equipped with this motor tube and the fins linked below on 7/15/2023 on an H210 Aerotech RMS motor. You can see for yourself that this is a very reliable design. Having the ability to lock…
UPDATE (01/12/2025) - I've added a more traditional nosecone for this model which is the same (in scale) as the FatBoy nosecone. The existing AV Sled or Plug will work in either nosecone. ----------------------- This is the Menace. It was…
UPDATE (08/15/2023): I have flown several launches with this mount and even with zip-ties, there is still a little bounce/rattling. I suggest you shim the camera with the zip-tie cutoffs or other thin stock (left-over balsa?) until I can…
This is a simple thrust ring, designed to slip onto the end of an Estes 29mm motor. I don't normally fly Estes BP motors, but when I do, I have to use the tape method because I do not put thrust rings in my motor mount tubes. Ever. This…
Update 08/04/1014: Updated the model to fix a small gap/void in the base of the support. REF. v1.1 The Classic Design Model Rocket Display Stand is a remix of a park bench created by Triple G Workshop . It was designed to accommodate…
Introduction: Inspired by the 4-in Crayon Bank Rocket, this rocket was designed from the ground up to be a park flier and/or show-stopper at your next club event. The Extreme Series of Builders Kits were designed for easy printing,…
Building off of a great design, I customized the ebay sled to work with my specific requirements. This is for the 3-in scaled-down version that I remixed. Here are the modifications I implemented: Opened up the hole in the threads to…
This is a partial builder's kit for a printed Der Big Red Max. I used the dimensions from an upgrade kit that replaces the balsa fins with 1/8-inch (3.2mm). I also created three different centering rings: Forward: Has a 6mm hole and a 3mm…
I made some adjustments to accommodate a Runcam2 camera
Introduction: The WAC Corporal model was one of the first models I printed. I printed, built, and flew it in one day and it was amazing and flew several times, until a tree ate it. I went back to my evil lab and began work on a few things…
Comgrow T300 Camera Mount Update : 5/11/2024 - I have been using this for almost 2 months and I have had no issues. It puts the camera in a place where I can see the nozzle and moves with the z-axis so I can watch even the tallest prints…
These are helpful couplers for joining rocket parts together. I try to stock parts for scratch-building my rockets and cardboard couplers are much lighter. However, I am also cheap and since I have the 3D printer, I use it when it makes…
This is a minor remix of the One-Piece Printed Glider by pittance for attaching to small Class 1 rockets (typically A-C sized motors). There are two sizes for the lugs to attach the glider to the rocket. This is untested. The modification…
Introduction The Mystic is an upscaled clone of the Estes Majestic Pro Series II kit. It includes all the parts to build, minus the tubes and other accessories. Below is an overview of the parts, print setting recommendations, a list of…
These models are the before and after STLs used in my “Lets Build…” series . The one named, “sample nosecone” is just over 376mm tall. The second model is the STL that has been split at 200mm, as detailed in the video. These nosecones are…
Introduction This is a “kitbash” of sorts. I took the best (IMHO) parts of each 3D project and smushed them together into a model rocket that just terrorizes the Colorado landscape. This is a builder's kit in that you need to have a fair…
This is a model for a thrust ring that will fit flush on the aft end of an Estes BP motor. It is designed to replace the wraps of tape that are commonly used to create a thrust ring on the motor itself, and mimics the thrust rings…
This remix simply adds some creature comforts to the Arogen67 model. I have added a coupler, a nose tip plug that will accommodate a ¼-in eye bolt, and I have also integrated the plug into the nose cone (3 models total). Important Note:…
This is a remix of the Arogen67'sBig Red Max Nose Cone, IPL's 4-inch Nose Cone Ebay, and my modified nose cone coupler, incorporating the IPL base. It replaces the existing ebay with the one from IPL including the base. You can learn more…
This bulkhead is designed specifically for LOC/Precision 4-in (102mm) body tubes. It was designed specifically for use with my 4 inch coupler but will work with paper couplers of the same size. It has been tested to work with Apogee 4-in…
This is a variation on UnknownPro's Goblin stands (which I use). There are lots of stands out there but the aesthetics of this one brings joy to my dark and dreary world. However, I don't build rockets with motor clips (Friends don't let…
This is a model for a thrust ring that will fit flush on the aft end of an Estes BP motor. It is designed to replace the wraps of tape that are commonly used to create a thrust ring on the motor itself, and mimics the thrust rings…
05/20/2023: Updated - The stand-offs were a bit off, so I moved them to the perfect location. Also, when using an eyehook for the shoulder of the nose cone, there isn't enough clearance so I adjusted this. This now incorporates 4 versions…
The original model is really loud. You probably should have earplugs or something covering your earballs. I just made it more obnoxious by adding an 8mm sphere inside. It doesn't work quite as well as a cork sphere found in manufactured…
I wanted to use my Eggtimer Quantum in smaller rockets and needed a way to secure it and a small 2S LiPo battery safely. I found the Arduino Nano holder by HD_Creator was nearly the same fit, so I downloaded it and used it as a reference…
