This is a remix.
Improved the strength of the part, reconnected the spindle to the shaft (was weirdly disconnected) and added a rim to the end of the spindle to help catch the spool if it gets shaken to the edge. Also included a mirrored version so that you can print the optimal orientation for your printer. Clips over the top frame extrusion and has a hole in the top for an M5 bolt and T-nut to fit into.

Recommend printing at 15-20% infill.
