I created this watch mount for my pulsemeter watch (ONRHYTHM 500 KALENJI). I made it configurable so feel free to adapt it for your needs.

My handlebar is 32mm wide so I generated 2 STLs for it: with and without a cable channel. Besides that I generated an STL for a 1inch handlebar.

Please note that the OpenSCAD script requires a lot of time for generation. It takes about 3 minutes on my machine.
