Spool upcycling, make a stackable Storage for your bits and pieces

I was thinking about how to recycle my empty spools and have decided to make a small parts storage from them. Good way to use up those “only little left” spools, too.

There are two different models, one with a separating wall in the middle and one without. the models are both 83mm high, so you can cut them down in the slicer to the spool width you want to use. I used M3x10 screws to mount them into the spools.

outer diameter is 200mm, inner is 107mm

There is also a gauge for the drilling of the holes.
