Filament Spool Feeder System
Description
I wanted a different way to manage my filament spools that were sitting on top of my lack table enclosure, and disliking most of what I found I redesigned some of the things I liked more into this. Mounted onto this Lack table enclosure https://www.thingiverse.com/thing:2864118 with leg extensions https://www.thingiverse.com/thing:3358702 to provide room for the Prusa MMU. The pass though parts are designed for a 2" thick surface. I've also modeled a drill guide to help you drill a 3/8" hole perpendicularly through the surface. There are two versions, the normal one has a break for the ptfe tube in the middle and uses magnets to connect a second tube coming from the top. The one labeled 4mm lets the ptfe tube go all the way through so you can run it all the way to the container. There is also a part labeled tube cap that can attach to the tube end part with magnet, the same feature is also on the box passthrough outside part if you want to use that, but it kinks the tube an awful lot and may not be suitable for all filaments. My only complaint is that the spool holders roll too smoothly >.> and some filaments are actually springy enough to unwind some of the spool, combined with the mmu feeding back on to the rolls... So I'm going to see if I can design a ball bearing hub for these with an integral spring to maybe make it wind itself back up, unfortunately by adding tension to the entire system... The central ball bearing spool holder is a modification of https://www.thingiverse.com/thing:1426106 The mount for it is based on https://www.thingiverse.com/thing:2778707 Parts (Quantity for a single spool container): 1 x Rubbermaid 21-Cup Dry Food Container - https://www.amazon.com/gp/product/B011CP3KDU 2 x PC4-M10 Male Straight Pneumatic PTFE Tube Push To Connect Tube Fitting - https://www.amazon.com/gp/product/B01MQDI4TM 1 x PC4-M6 Male Straight Pneumatic PTFE Tube Push To Connect Tube Fitting - https://www.amazon.com/gp/product/B01MQYJ9T6 1 x Hygrometer Thermometer Digital LCD Monitor - https://www.amazon.com/gp/product/B07BLY177S 4 x Round Neodymium Magnets, 10 x 2 mm - https://www.amazon.com/gp/product/B0753ZPBLQ 6mm Airsoft BBs - https://www.amazon.com/gp/product/B001L1W4B0 4mm OD PTFE tube, approx 300mm long 8 x #4 x 3/8" Flat Head Wood Screws 4 x #8 x 3/4" Flat Head Wood Screws
