Feederbot (DIY Filament Rack)
by muckychris, published
I made a filament rack and wanted to share the parts list and diagram so people could make their own. I spent a long while testing with spool sizes from all the usual suspects and this setup seems to work well with all.
The 3/4" pvc pipe (actual outer diameter 1" or 27mm) fits the smaller 33mm spools (Octave, MatterHackers) and the larger 52mm spools (MBI, Protoparadigm).
I sell this rack fully assembled and it includes the red threader cap that cleans the filament in some of the photos. Unfortunately since that part is patented I can't share it here. (http://www.feederbot.com)
3/4" PVC PIPE
You can use hardware store 3/4"PVC Schedule 40 pipe.
I use furniture grade PVC pipe - it's much more expensive but the high gloss finish produces very little friction when the spools are doing their thing.
I suggest dry fitting all pieces THEN use PVC pipe cement on all parts.
The cement dries in 30 seconds - so be careful with this step.
In total you will need 1 x 10' length 3/4" PVC pipe cut down to:
1 x 15" (front foot)
1 x 10"
2 x 8"
4 x 7"
2 x 6"
2 x 5"
6 x 4" (5 of these are the spindles that the spools hang on)
2 x 1.5"
4 x 3-way elbow
5 x tee
1 x cross
3 x 90 degree elbows
5 end caps
