prusa mmu2 buffer 3d models

UPDATE #3 05.09.2019 - For the latest solution using this bracket see https://www.thingiverse.com/thing:3845698 My approach to a wall-mounted spool holder for the Prusa i3 Mk3 with MMU2 unit is straightforward. I had three key requirements in mind -...

... just a remix of the mmu2 front mount design from WhiteBULL. ...The redesign consist of the frame base mount to support the mmu2 from underneath. The part is compatible with the main 1 part from WhiteBULL. ...I didn't use any support to print the part.

I used these PC4-M10 PTFE Fittings for 4mm PTFE tubing. I used this 3mm ID x 4mm OD PTFE Tubing but the stock 4mm tubing will also work. Replaces the compression plate on the MMU2 with actual PTFE fittings. I needed this to switch to 3mm ID tubing,...

The original Prusa Spool Holders for MK3 + MMU2 is taking up too much space on my table. I only have room for three, so something needs to give. I got inspired by the design of "RNLDNKP," and I came up with a brand-new spool holder that sits right...

Simple to load and unload the filament is a buffer from the original Prusa.

<p>With this guide, the short PTFE tubes can be clamped in an angle of 45° with a screw. ...Easy and fast to print with little filament. Can be securely fastened with 2 screws on the Ikea Lack Table. No filament buffer is needed with these.&nbsp;

So, the mmu2-s-holder-base_rework2.stl essentially replaces mmu2-s-holder-base.stl: it's compatible with the other official parts that are screwed onto it. I also created a tube to pass through the wood; it is designed for a 6mm hole in the wood...

Rob In preparation for my upcoming MMU2 (ordered since Oct17), I've imagined a solution for an extremely relevant problem many people will face with the MMU2. Each time a filament is parked, it's retracted to the MMU2 unit, pushing about 300mm of...

It also includes a 2-axis filament guide with a securely insertable PTFE tube, designed specifically for MMU2 upgrades. ...Additionally, two threaded mainshafts, with or without bearings, are offered; for the bearing version, HK1012 needle rollers and...

For some reason some of my filament seems to roll over in the MMU2 spool holders to form an overlapped loop on unloading. When the MMU2 pulls the filament back in for the next load the loop rolls over on itself and can snap or form a little knot. I...

When the MMU2 pulls the filament back in for the next load the loop rolls over on itself and can snap or form a little knot. I found that having small vertical obstruction next to the loop will bump it over into an opened up loop instead of the...

Replacing M3x30mm socket head cap screws with M3x40mm allows for easier tensioning of MMU2 idlers and opens up the unit's design. This modification involves swapping out existing screws, which are then secured in place using CA glue, while a friction...

Second iteration of my wall-mounted spool holder boasting five individual threaded rods with tapered fasteners that effortlessly accommodate most standard spools for swift replacement, engineered specifically for MMU2 upgrades. ...I crafted reinforced...

A wall-mounted spool holder features five individual threaded shafts and tapered nuts that accommodate most common spools for effortless replacement, accompanied by a 2-axis filament guide where the PTFE tube can be securely inserted, specifically...

Fixed it and it finished with no issues (.2mm height, Chris Warkocki's MMU2 Pretty PLA V1.2 profile, my tool-change and ramming settings) - Dark Souls knight with BVOH interface supports (50% scale, .15mm height, Chris Warkocki's MMU2 Pretty PLA V1.2...

I'm experiencing an issue with my filament rolling over in the MMU2 spool holders, resulting in an overlapped loop when unloading. Upon retraction, the loop rolls onto itself and may snap or form a knot. To prevent this, I've found that introducing...

This is a Magnet improvement to the MMU2S (R2) Selector PINDA part.The only modification, I made, was to place a 6x1 mm round super magnet under the steel ball and filament path.This magnet will keep the steel ball down when the filament is redrawn.

Replaces the compression plate on the MMU2 with actual PTFE fittings. I required this to switch to 3mm ID tubing, as the stock way was not holding the softer tubes securely. I extended the threaded region to strengthen the part compared to the...

This modification makes maintenance of the filament selector for the MMU2(S) significantly simpler. To detach the selector, one must still remove the screws securing the selector's stepper motor in place, but removing the selector rails from either...

I mounted my MMU2 horizontally because I typically place the printer on top of a lack table with spools inside unless I need to print something warp-prone, then I move the printer into an enclosure and put the spools on top for easy access. However,...

This is my take on the PFTE tube organizer for the MMU2. I've designed it to be versatile and easy to assemble. To get started, you'll need to print two of each tube separator. This will give you a total of four pieces that are 3mm x 10 mm in size,...

... like these: https://www.amazon.com/gp/product/B01IB81IHG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1&tag=tv-auto-20. Many thanks to jzkmath for maintaining the step files repo of Prusa i3 MK3 on GitHub: https://github.com/jzkmath/Original-Prusa-i3.

Hogwarts Shield for Multi-Color Prusa Printer (5 Colors). This shield isn't designed to print separate parts and then glue them together. ...It's meant for a printer with the capability of using five extruders.

Bottom Edge Pieces for the MMU2S Enclosure from 3DUPFitters. I didn't like how the bottom of this enclosure didn't retain its shape terribly well, and it slid all over the desk - plus for me at least one edge wasn't quite flush with the desktop. The...

I will get some up when I print them out. The MMU2 is not particularly Lack Enclosure friendly due to the added height and mounting angle using the provided brackets. The angled mount is necessary to maintain the 210mm printable Z Height but if you...

I had my first experience with bad prints due to moist filament since I installed the MMU2S kit. Because it is such a pain to thread the five spools, I was leaving them out. With a single spool I always put the filament back in the ziplock bag and a...

Replaces the PTFE holder (screw on compression thingy), with M10 couplers. You will need PC4-M10 passthrough fittings like these. https://www.amazon.com/gp/product/B01IB81IHG/ref=oh\_aui\_detailpage\_o00\_s00?ie=UTF8&amp;psc=1&amp;tag=tv-auto-20...

... Printed fine for me on my Prusa in PLA and could use any filament type. ... If shrinkage causes holes to be too small it deforms the tubing then either ream them out with two halves clipped together or print again and make it bigger in the slicer.

The absence of italic font was a bit jarring for me as well, especially since all other "Prusa" markings on my printer were not in italics. Happy printing, and don't forget to give kmccon a like for his outstanding work on the original design! ...His...

Taking directly from the Original Prusa Step file, this frame mount has been specifically designed for the Bear Full Frame. I've neither printed nor tested it yet, relying solely on measurements taken in Fusion 360. Any suggestions or advice would be...
