What is included here are the files that you need to print to get the dual lock, which is the Idler Body, the Pulley Body, and the right Lock. You need an extra M3x35 screw with a spring and an M3 square nut, that you should have gotten…
Remix of the MMU3-Holder to hang in in various angles
Hello, in my setup, the filament loading process is a bit complex due to limited space and the presence of a filament dry box. However sometimes I just want to print a tpu or some almost empty spools. Therefore, I wanted to find a way to…

As of July 5, 2024 the official GCODE for printing the MMU3 printable parts is done with the Print settings configured for ‘SPEED’ rather than ‘QUALITY’ and makers (myself included) have reported problems using the provided file. This…
The Big Einsy case is an awesome concept. This remix addresses the issue of being able to easily access the frame fixing screws, especially after assembly. A channel against the frame has been opened up to route a +5V power cable up to a…
This is a remix of the original mmu3 frame holder in order to gain slightly more overhead clearance above mmu3 body. The selector is partially hidden behind the selector, but still can freely move to both ends. I don't remember the…
Testcube for mk3s with mmu I also use the test for the different shrouds - you can see from the sphere how even the air distribution is
I had to replace the wheels on the MMU3 spool holders, those plastic ones weren't smooth enough and I repeatedly had spools being kicked out, this is much better now. For each spool holder you'll need 4x started 20mm skateboard bearings,…

CHANGELOG Main Instructions follow. 30/10/25 - Added spoolholder_spindle_mk4, spoolholder_roller_mk4 and buffer_mk4 by request. To keep things simple, these versions cut away some material to get them to fit on a MK4 bed. Reported to…
I colored parts with my kids, ideal for MMU3 - printing time on MK4 is 14h.
Holds your PTFE tubes from the MMU2/MMU3 nicely parallel - which helps to reduce friction. The part does not actually clamp the hose, but the friction should be enough to hold it in place. The model allows you to choose either an M3…
This unit is to replace some of the stock MMU3 buffer while using the new cassette system. I have included a bracket to hang the buffer assembly from the back wall of the enclosure but it may not allow the proper clearances as I have not…
PTFE tube fitting (Collet) for the MMU3 Cassette assembly, i went into upgrading my MMU2s to MMU3, upgraded from official printed parts, had almost everything in my inventory except for the collets, searched online stores but could not…

This is a simple model designed to test the Prusa MMU3. It uses all 5 filaments to create a palette identifying each spool by its number. Its definitely not the prettiest model you will print with your MMU3, but it is certainly useful to…
Remix of the great, compact filament buffer by @Paul_75970 that makes it compatible with the MMU3 R4 cassettes (Version B). Since I also wanted to use the remix of R4 cassettes , I couldn't use @mikedmor remix which squishes the…
Because the filament is fed into the MMU unit at quite an angle in my buffer arrangement, I sometimes had the problem that the filament was pulled in by the pulley in such a way that the Idler output PTFE tube was not met (indicated by…
Introduction This is a piece I made to test the Prusa MMU. It uses all 5 colors, and you can change the color to your liking in PrusaSlicer." Remember, you can change the color using shortcut keys 1 through 5, provided you've previously…
Threading the filament into the buffer is still very awkward for me. You have to remove the segmenter, thread the filament around the roll and then push it up to the MMU, start the loading process of the MMU and then reinstall the…
Update 16-Jun-2024 : With the amazing contribution of @poelstra_2112725 on MK4 with MMU3, we have achieved more than one color changes per test print, to a maximum of four. Amazing idea to print the numbers before the purge block so that…

After assembling Sam's very tidy MMU3 Community version, I decided to make a few slight modifications to save space on the width of the whole unit. The main modifications are: Buffer Cover: Reduced width by around 2mm. This saved some…
In early 2025, I replaced my two PRUSA MK4S printers with two PRUSA CORE ONE printers (one assembled and one kit). The second MK4S printer had the MMU extension; I kept this accessory to remount it on the one delivered as a kit. I…
Here is the part that is missing from the MMU2 & MM3 kits. The thing often referred to as "the button" in the manual. The reset button. No more looking for something long and small to press the button with. Its a 4 minute print…

I modified the plate holders to be able to mount them with 3.0mm screws. This way I was be able to mount it straight on my Ikea Lack enclosure. Now I am be able to feed the filament from my repbox on top, to the back side of the Ikea Lack…
I needed to align PTFE tubes in different quantities than the 5 of the original Prusa MMU3 clips. On Printables I found the PTFE tube clips by @Samotrel , which were close to what I needed, but they don't tighten the tubes enough and they…

I upgraded from MMU2S to MMU3 , but the MMU Label Plate file seemed to have no text for multi-color printing, so I made a copy as close as possible to the original. Printing is very simple, right click and split to get multi-color printed…
Here's a video I made on improving MMU2 reliability Very simple model to pass PTFE tubes through your Original Prusa Enclosure. The printed part is a loose fit in the enclosure and there is a press-fit retaining clip to keep it in place.…

MMU3 Buttons which perfectly fits micro switches and MMU3 electronics lid. Printed from Prusament PETG
I wanted my MMU3 buffer and spools to be entirely contained within the Prusa Original Enclosure. So I made a few parts to help: Buffer plate holders to use as mounting brackets (above or below the hinged lid) Filament guides for both…
According to the MMU3 assembly instructions , you shouldn't print your own Nextruder main plate! Instead, Prusa recommends using the one supplied because FDM printing cannot produce the same quality. The kit also comes with an extra main…
This is my take on a ‘lite’ CORE One MMU3 upgrade, but one that allows use of the stock top cover and vents. The MMU3 unit is angled flat and moved down a bit, leaving the filament to skim the top of the case, and the cover is raised up…
update october 2023: I added new optimized version V2. This works a little bit better for me. Feedback are welcome. I recently got my MMU3. Unfortunately, threading the filament into the buffer is very difficult if you have to hold…
Here are the fantastic Minions created by Heidi Makes ( @erikaheidi ) with coloring added using Prusaslicer. The 3MF is configured for four perimeters and 140% of the original size for added strengh in the arms and other thin parts.…
Note: This profile is no longer being worked on. This profile was originally created because many people requested a Prusa MK4 with MMU3 profile. I don’t own a MK4 myself, so the profile is untested by me. While I did receive a bit of…
I wanted a better indication of what filament is currently loaded. So I designed this pointer, which you can simply put on top the selector front plate. It is held by friction. No supports needed Designed for 0.2mm layerheight and 0.4mm…

I wanted to remove the part of the buffer holder that goes under the printer so that it could be mounted on the side of my enclosure.
This modified/kit-bashed buffer segmenter (front plate) for the MMU3 cassette buffer, in combination with @Melvin_131612's excellent MMU3 buffer mount allows the buffer to be mounted horizontally, lying down on its side. I made this…
