PRUSA MM Y-Multiplexer without Steel Tubes

thingiverse

The PRUSA MM (Multi-Material) v1.0 Y-Multiplexer uses steel tubes for a smooth filament pass-thru and it functions perfectly... but if your filament is imperfect or too soft, then it will get stuck in it and the nightmare begins. This part is based on an idea shown in https://www.thingiverse.com/thing:2740929, but since I had a difficult time trying to remix it, I decided to create one from scratch using it as a template along with the official Y-Multiplexer. The differences between https://www.thingiverse.com/thing:2740929 and this part are: - Inner tube length - Inner tube angle - Support for Heat Threaded Inserts (https://www.amazon.com/gp/product/B077CG1W3L/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) - Spacing optimized for PC4-M5 (https://www.amazon.com/gp/product/B01N6JF205/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) - Diagonal end for insert. You may need to adjust it so your inserts fit properly. I created it using Adobe Fusion 360 and I have supplied the "Archive" (f3d) file if you need to edit it. I just began working with Fusion 360, so don't judge me if you do not like how I structured the file!
