Customizable Filament Gland v2

thingiverse

Storage box filament gland with two holes. This version has a customizable number of filament openings and solves several issues present in the earlier design. 1. It's now easier and faster to print, requiring no supports whatsoever. 2. Filament moves through it more easily than the previous version. When assembling this model, cut a short length of PTFE bowden tube slightly shorter than the center post itself as seen in the first picture. This piece fits between the festo fittings and keeps the filament aligned properly. Hardware Used: * M5-0.8 heat-set inserts (6x per pair for singles, add 2 for each additional filament post) - https://www.amazon.com/gp/product/B0754MY5H8 * M5-4 push-in fittings (2x per post on each gland) - https://www.amazon.com/gp/product/B00RN3KKWA * M5-0.8 screws of sufficient length (4x per pair, I used M5x10mm) Assembly: Four M5-0.8 heat-set inserts are inserted into the corner pieces for the "outside" parts. Two M5-0.8 heat-set inserts go into each filament post from both ends. Use the drill template piece to drill holes. A 5mm twist drill is used for the corner screw holes, and a 5/8 inch forstner bit for the center hole. The holes drilled don't need to be exactly the right size as long as the plate still covers them. Once the inserts have cooled slightly, insert a short piece of PTFE into each filament post, then thread an M5-4 push-in fitting into each end. The PTFE tube should be short enough to account for how far the fittings thread in so that they do not compress it, which will cause the filament to bind up inside the post instead of sliding through freely.
