Ender3 Side Mount Spool Holder (no-spindle)

This filament spool holder relocates the spool to the side of the machine for a more direct filament feed into the extruder, or when space above the machine is limited (as was my case).

It doesn't require any mounting hardware – simply pop the plug off the back of the base extrusion and slide it into the slots.  

However, it does require this spindle from AngryHulk ("mounting_clip" not required):

If you're fresh out of 608 bearings (required for the spindle), these worked well for me:

If you'd rather try a 1-piece design with an integrated static spindle, try my other version:

Compatible with spools of up to Ø200mm OD.  Any larger and the spool will interfere with the x-axis motor.

Verified to function with an Ender 3 Pro, but it may be compatible with other machines.  I printed it in PLA with a 0.4mm nozzle, 0.3mm layer height, and 5 walls all-round.

Orient the part on the build as shown in the photo.
