Modular Compact MMU2 Buffer

Here you have my own MMU2 Buffer version. I have used it almost one year without issues.

Features:

+ Compact size. + Fast and easy to load and unload filament. + Switch to lock and unlock the drawer easily. + Screwed feet (TPU). + Cool design. + Multimaterial versions. + Designed to fit on an enclosure (55x55cm).

The only hardware needed are one 608 bearing and three PC4-M10 (passthru) connectors (https://www.amazon.es/gp/product/B078SLGZ42/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1).

I recommend to use PTFE tube (ID:3mm OD:4mm), for better results with MMU2 unit. I'm using two PTFE pieces (lengths: 25cm and 15cm)

This buffer has been designed to be used mainly on an enclosure, but can be used on other situations.

Please print files in the orientation provided. There are 3mf files with printing parameters and custom supports.

Optionally can be used with:

I have included my "enclosure wall" to fix all buffers better to the upper part of an enclosure.
There are two multimaterial versions to print MMU2_Body in two colours.
