About this 3D model
4mm PTFE / Bowden tube inserted in rear and you have a simple spool holder. I enjoyed https://www.printables.com/model/422216-ikea-skadis-filament-spool-holder-voron-style for a while but found I used it so much it started rocking around and getting loose due to just being on two pegs. It was easy to knock off the skadis when adding/removing the spool. I started from fresh with Voron github cad files and Rod's fusion file to assemble a quad peg robust boiah. When you cut your PTFE tube check it's flush and not proud of the back to it doesn't catch vacant skadis slots. Trim it just right though and a micro bit of ptfe tube sticking out can actually be like a rubber pad (of flexy tube end) that kinda helps grip it all on the pegboard nicely lol. Print on its side for spool holding strength, supports re-quuuired ! I did PLA 5 perimeters lol because skadis pegs break too easily in general and I like this design and want it to last. I didn't design the pegs but needed to sand/file off the support interface remnants fully to get it onto the skadis, so be aware it's not a loose fit.
