"A Simple 3D Printed Scotch Yoke Mechanism" is a model I designed for a mechanisms class. The motor used in this model is an N20 60RPM 6VDC gear motor powered by a 3VDC battery pack, thus the motor runs at approximately 30RPM. With the…
I designed this case for the "Lilygo T-Display-S3 Touch Development Board" which features a 320 by 170 color display and a touch screen. I'm planning on using this board in upcoming projects and decided to create this case for it. In…
Our youngest son sent me a video of a wrist watch that he found interesting and wanted to know if I could explain to him how it worked. Well that would be too easy (for my ego at least, or maybe I'm just being played? ), so instead of…
"A 3D Printed Kinetic Marble Machine" is a relatively easy to 3D print and assemble kinetic model featuring a two piece "print in place" dual axis gimbal mechanism. The model is constructed of ten unique 3D printed components (eleven…
Designed as a science fair project for the grandkids, this model can be used as just a 3D printed runaway escapement spring motor demonstrator, or with the additional drive components, a 3D printed runaway escapement spring motor car. The…
"Marblevator Pick and Place, Version 4" is my fourth pick and place based Marblevator. This model utilizes four 3D printed TPU "fingers" to pick up a marble from the end of the track and place it at the start of the track. The fingers are…
"A Simple 3D Printed Whitworth Quick Return Mechanism" is another model I designed for a mechanisms class. The motor used in this model is an N20 60RPM 6VDC gear motor powered by a 3VDC battery pack, thus the motor runs at approximately…
"Self Reversing Screw Mechanism, Walking!" utilizes the self reversing screw mechanism from my "Marblevator, Self Reversing Screw Lift" model to create a walking mechanism. Instead of raising and lowering bucks as in the Marblevator…
As I've previously mentioned, my wife loves hummingbirds. By happenstance, after completing my previous two whirligig models, a Youtube follower asked if I could convert my previous hummingbird electric motor driven model into a…
All of the Marblevators I've designed so far had a mechanism to move a marble from the end of the track to the start of the track. "Marblevator, Tracks" takes a different approach in that the tracks themselves move in concert so that the…
I've created many "Marblevators" using various lift techniques to lift a marble from the end of the track back to the start of the track. In "Marblevator, Self Reversing Screw Lift", I've designed a "reversing screw mechanism"…
"Self Reversing Screw Mechanism, Slinky!" utilizes the self reversing screw mechanism from my "Marblevator, Self Reversing Screw Lift" model to take all the work out of using slinky toys! As usual, I probably forgot a file or two or who…
"Marblevator, Buckets" uses a carefully timed two bucket lift mechanism to transfer 11mm nylon spheres between the end and the start of the track. The track starts with a large downward spiral segment that transitions to two straight…
How many mechanical components are necessary to lift a marble from the end of a marble run track to the beginning? Well in "Marblevator, Rube Goldberg Style" I added as many as I could to create this Rube Goldberg / Erector Set themed…
"Marblevator, Simple" is more than likely the simplest Marblevator I've ever created. Consisting of only two easy to 3D print components along with a gear motor, ball bearings, battery pack and batteries, this model is, well, simple! The…
Parts. I acquired the following parts: • One N20 6VDC 60RPM gear motor. • One 4AAA cell switched battery pack. • 11mm nylon spheres. I 3D printed the following parts at .1mm layer height, 20% infill and no supports: • One "Base.stl". •…

My old chop saw finally gave out so Santa brought me a new one! For repeatable cut lengths of stock, I previously had to attach clamps and blocks of wood to my old chop saw which made it difficult to attain accurate results. For my new…
"A Mostly 3D Printed Escapement Mechanism" is a model I've wanted to design for quite a few years. Having no experience whatsoever in horology, I finally decided to step up and design my first windup escapement mechanism. As usual I…
An inductively rechargeable version of my Angel Tea Lamp design. When the angel is placed on its charging base, the tea light LED extinguishes and the angel internal lithium battery is charged. When the angel is removed from its charging…
"Marblevator, Keychain" is perhaps the simplest of all my Marblevator designs. Consisting of a single 3D printed in place Marblevator and a single 4mm diameter ball bearing, this Marblevator is "keychain" ready in a few simple steps. As…
Introduction. A follower challenged me to make the fastest Marblevator I could, and here's my first attempt, "Marblevator, My Fastest Yet". As usual I probably forgot a file or two or who knows what else, so if you have any questions,…
Of the many, many things regarding electronics my father taught me, one of the more unusual was using a phono plug and jack as a "slip ring". While slip rings are indeed commercially available, I thought it would be fun to use his phono…
