Fixed spool holder for closed enclosure with opening lid

thingiverse

Fixed spool holder with bearings for smooth rolling of the spool. I designed this for my Prusa enclosure so I can fully open the top lid while printing in progress and the spool doesn't fall over Printed in PLA Screw holes are 4.2mm. For the support side I used 4mm threaded bar since I don't have the required length, M4x27 is the minimum needed. For the end side I used M4x20 screws. For the base I used 2 wood screws I had, but these can be any type. I will replace them with something more sturdy, for now they're doing the job just fine. 8 bearings also needed for the spool to roll on, 4mm inner diameter and 13mm outer diameter. Partial supports only needed for the spool support. Later edit: I also added a printed spool support, this one works as well if you don't want to bother with bearings. Holes are 3mm wide, but I recommend using 4mm screws which go directly into the plastic. Print with 3 perimeters, 15% PLA works fine.
