The OpenSCAD file is currently a mess, and I am still designing bobbin carriers. But its still cool :)
You will need:
Various M5 (25mm, 40mm) and M3 (~30mm) screws and nuts
The OpenSCAD file scales to your imagination. But it might take playing with values to see what they do, in case the naming is confusing (and right now it is...).
Bobbin carrier design
Cleanup and modularize the OpenSCAD
Make multiple designs (for those with small and large printers)
