I needed a support to place my cell phone on the tripod and after not finding any that made me feel confident I decided to design my own.
Some things to take into account is that the support has a built-in tripod thread, since in Spain it is quite difficult to find 1/4 inch nuts. Also an 8mm M3 screw is needed to attach the wheel to the threaded rod.

Print instructions:
Recommended 0.2mm layer height.
All parts should be printed in the default orientation for best results.
It is recommended to print the rod with a brim of 3-4mm.
The bottom part contains a 0.2mm layer on top of where the wheel is located to allow for unsupported bridging. This layer must be cut once the part is printed.
No support needed.
