Thanks for sharing !
I just finished my rotating 32" TV for my upcoming Pedestal Arcade cabinet using a 12V gear motor, an Arduino + Driver and as well 3D-printed parts for most of the mechanical and electrical mounts. UNBELIEVABLE helpful, when you can create parts exactly for your actual needs. Interesting, I did not think, that a stepper motor could be strong enough to move and hold a 27" TV !
