Moustache safety razor cap

Named "Moustache", this protective cap is designed to fit your Gillette King safety razor.

As this razor is pretty similar to models from other brands (like the Merkur DE head, for instance), it might also fit them. 
If your razor's head dimensions are close to 41.5x25.3x8.7 mm without blade installed, you can give it a try.

You can even store some spare blades in the top compartment, which has also a top hole to ease their ejection with your finger.

I presently work on a V2 version to add a "razor stand" feature, but I haven't managed to get a good compromise between simplicity and stability yet. I keep you posted.

Note: I print it with PLA and a 0.2 layer height without any problems. No need for brim.
