thingiverse

Here are the parts needed for this project: 2x 6mm threaded rods, each approximately 150mm long; 1x 8mm threaded rod or bolt with nut, also about 150mm long; 8x 6mm nuts; 4x 6mm acorn nuts (optional but a nice touch); 8x 6mm washers; and 2x 22mm bearings. Additional 3D printed parts are required: 2 of them. This project was designed to make changing the spool as fast as possible, with the entire top section removable using only one nut.
