Yet Another Universal Spool Holder

I just can't seem to find a spool holder that fits my need. So I guess the world needs yet another universal spool holder design. Here's my take on it, specs:

• very sturdy, printed at just 15% infill and 0.2mm layer height
• fits all spools up to 1kg (lemme know if otherwise!)
• prints with minimal or no support
• easy to install and uninstall
• modular for remixability
• snug-fit 6301LU bearings (just push in, or hammer in)
• FreeCAD source files included (sorry it's a bit messy)
• pretty!
