Minimal Corner Hole Templates for Ultimate Cereal Filament Drybox

I liked xeemz's idea of a drilling template for GunplaMark's cereal dryboxes, but it was still wasting too much filament, and it was difficult to distinguish between Back and Front.
So I removed as much excess plastic as possible (without compromising structural precision) and engraved tags stating “Back” and “Front” into the parts.

The end result is that those parts now need only 25g of filament each, down from 60g in the previous version (and 100g in a real drybox part).

Minimized filament consumption, and added embossed inscriptions to distinguish Front and Back.
