2018-05-27 Update: I've edited the holder a little bit. The portion around the screw head is beefed up (old version cracked sometimes) and the complete holder ist stiffer.
Nice litte holder for SIGMA Bike Computers. I made it for my needs, maybe someone else can use it as well. It's designed to fit handlebar diameter 31.8 mm and to be close to the clamp. You'll need 1 screw and 1 nut (M4, metric).
The STL is slightly different to the pictures, I've already improved some details. And I had my name on it, but of course I uploadet a plain one.
