Variations on Parts Bin Inserts for HatchBox Filament Spool

I'm using Aaron Nance's Hatchbox spool storage system to organize my Lego, and I needed more variety in the size of drawers, so I remixed the model to have various heights and widths.

For the half-height drawers, this is what worked well for me:

1. Screw the bottom drawer to the spool first
2. Cut about 5cm of any 1.75mm filament and insert it in the top end of the screw hole
3. Put the top drawer in place by setting it on top of the bottom drawer after inserting the other end of the filament in the bottom hole
4. Screw in the top drawer
