The boxes are used to store my tap sets, complete with the appropriate drill. 

The original is here: [https://www.thingiverse.com/thing:1201466.](https://www.thingiverse.com/thing:1201466.) The design is ok, but I made some minor changes:

• Changed RoundedBox to RoundedCube (the former is deprecated in newer MCAD versions),
• Made the lid slot larger to save filament, and optionally make it transparent,
• Fiddled with lid location to make the changes to 'snugness' and 'lidSnugness' visible,
• Optionally add a reinforcement at the base of the divider walls. Thin walls tend to get loose from the case bottom. 

The changes are not tested for a lot of configurations, so may require additional tuning.

Confusing is the presence of both 'snugness' and 'lidSnugness'. The former controls the
cutout in the box, the latter controls the lid.

The .3mf are the boxes and lids I needed, the .scad allows customizing.

BTW, the license allows you to store other things than tap sets in the boxes :-).
