I made this holder for my son's flip phone to screw to my family charging station.
I included the Fusion 360 CAD file export. The design is set up for WYSIWYG parameterization. You can double click on any of the measurements visible in design mode to resize:
If you don't want the screw holes just “suppress” in the timeline.
I added a bit of adhesive backed felt to keep the phone from sliding around on the slick plastic.
I printed in PLA with NO SUPPORTS, any material should do.
The author marked this model as their own original creation.
