Double Edge Safety Razor Handle Replacement

The metal handle for my razor is smooth, so it is hard to have good control over it. Other designs exist to print, but I wanted something with flutes instead of knurls, for ease of cleaning. I also didn't want to have to use a nut.

This printed part replaces the handle of the razor, which featured a female M5 thread. The thread will be printed and can be used as-is, however I had to use an M5 tap to get it loose enough to be easily removable for blade changes.

It works well.

Included is the freeCAD model.

UPDATE: 10 weeks later, this has been getting wet every day and been exposed to a variety of shower products, and hasn't gotten smelly or discoloured at all. It's ergonomic and I'm very happy with it.
