Harrys Handy-Halterung

thingiverse

The phone holder can be attached to the bicycle, for example. The phone is protected and securely fixed in the holder. As OpenSCAD allows easy parameterization, the holder can easily be adapted for any phone. Measure the dimensions of your phone, handlebar tube, and ground thickness, then input them into the SCAD file. Use OpenSCAD to create a suitable STL file. Print and attach with screws.
