Wire Spool Box

This is a bench top organizer for small spools of wire or solder. I have a ton of them all over the place and the get unruly. This is my attempt at organizing them all in the same place.

The 'axles' are offset in hopes of preventing the spools from colliding with one another.

The top of the box has a crude metric ruler without markings. I'd love to make this better.

This box is cut from 3mm plywood. I use Luau wood because a giant sheet of it costs $10 and they cut it down into laserbed sized pieces. (What is with people uploading designs that don't include material width? Or filetypes of proprietary software for that matter?).

The Axle holes are 5mm diameter to accomodate this 5mm(ish) aluminum stock I picked up at the local hobby shop for $2.

This is all rendered from openscad so please give me feedback on material width/axle size and I will glady provide the dxf's.
