Another egg-timer hyper lapse turntable rig - this one can hold a mobile phone.

PhoneClip-Half part needs to be printed twice.
Shim part is 1 mm thick. If you need another thickness - rescale only in Z-axis. Or print 1 mm, 2 mm and 4 mm shims already.

If you don't have any action cam holder bolt, look into my other projects and pick the thumb screw - you can then put it on M5 30 mm hex head bolt.
