Conical Spool Holder

thingiverse

I made a super-simple spool holder to use on my RigidBot. It only requires one ball bearing and can be used on spools of various sizes. The conical shape ensures a wide range of fitment options. Due to its design, zero supports are needed, making it single extruder friendly. --- ### Recommendations - Use only one ball bearing, mounted at the widest part of the cone. This keeps the spool rotating on its own axis and prevents binding. Plus, you can use 8mm clips to keep the filament from moving on the rail as it unwinds. --- ### Changelog **2018-04-27** - I made some adjustments to the recommendations. **2017-10-17** - The width is now automatically calculated from height, maintaining the same pyramid shape while only setting height. - I uploaded pre-made STL's for small, medium, and large spools with measurements in mm for height. **2017-09-09** - I first uploaded this design.
