Double Edge Safety Razor Blade Pack Storage Box

A box that is inspired by the 20 pack Astra box design that lets you store your blades safely with a level gauge on the side. It can keep any blade packs that are the same size as Astra packs (about 48.5 x 27.5 x 7mm) and has a capacity of 22 or something like that. 

The lid is not required and is not a tight fit, it's just to keep the water and dust out. 

Supports are required for the finger grabbing area.

PLA at 0.2mm works but so will every other material too, probably.

FreeCAD and STEP files are included, so edit to your heart's content. It's CC0 so do whatever you want.
