My wife was a little rough on her bike computer. As a result, it no longer sits firmly on the holder, no longer has safe contact and often even falls off when shocks occur.
This thing solves the problem.
Not pretty, but stable ;-)
Still no photos and no STL preview? Here it works as it should.
For best stability, the model should be printed in the given orientation.
I intentionally chose white PLA+ ... in the hope that it will retain its shape for longer than black PLA+ (on hot days).
