Flash Forge Filament winding tool

A tool I designed for winding Flash Forge filament spools. Most spools don’t fit in the FF Adventurer 3, so I have been winding from one spool to another. After my children no longer wanted to wind the spool, I realized I needed a better solution. Essentially, the teeth fit into the spool. The hex column fits in a 7/16” socket, which can be attached to a drill. Designed in OpenSCAD, worked on the first attempt after test builds on sub elements.
