25cm 360 Turnable Stand. I designed it for my future photoshoots and to evaluate my arduino uno that stands in a corner of my house. It could wobble sometimes but with a little gluing and fixing, this problem can be overcome. It works with arduino uno, 28bjy-48 stepper motor and 3 608zz bearing. While preparing this model, I also benefited from the free models made by others, I add the links below for reference.
