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.
The author marked this model as their own original creation.
