I had a variable number of wire spools which I wanted to easily “store” long term and take out so I could work with. So I came up with this “system” which can easily be chucked in a storage bin and taken out and put on a desk.

It consists out of three components:

• Base: print only once
• Holder: you can print this zero or more times
  • Holder: the actual case
  • Center pin: the “pin” that the wire spool rest on and screws into the base or holder.
• Lid: print only once
  • Lid: the actual lid
  • Screw: a screw that fastens the lid to a center pin.

You can change the parameters to match your stack of spools and print how ever many holders + base + lid. The models are FDM optimized so make sure you always have the big flat parts on the build plate.

No post processing involved!
