Endcap Lock for Filament Spool Holder

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5190343.

Add-on to Filament Spool Holders by 3DStartups.

End cap works as a cam lock to prevent the arm from disengaging prematurely. Cap can be pulled out with no effort, but once inserted, the spool holder locks together much better.

v2 uses a tighter tolerance than v1, so you can remove the top arm completely. This allows the filament reel to angle/turn as needed when spooling.

Both v1 and v2 can be resized +/- 5% in your slicer to get the fit you like. Good luck!
