razor with safety cap

razor blade holder with a slip-on safety cap

update: additional handle with a hole for a square nut M3 (thanks to Nutshell)

hello, here is a razor. needed are standard razor blades, a screw M3 x 20 mm (stainless steel) and a brass insert nut (M3 x Ø5 x 6 mm).
the screw is screwed into the upper part, insert the blade, put on the lower part and screw on the handle.
a cap protects you and the blade.
three different cap shapes to choose from:
1. without blade slot
2. more compact for one blade
3. with flat side for two blades
(watch the video how it works)
please note - do not insert unpacked blades into the cap.

the components are printed as they are stored as stl. layer resolution 0.15 - 0.2 mm. all parts are printed without support.
a brass insert nut is melted into the handle with a soldering iron.
