Rotating Table with 24BYJ-48 Stepper and 608 Bearings

thingiverse

I've been wanting a rotating table for a while now, and since I had that spare 24BYJ-48 Stepper Motor and Controller on hand (these come with various Arduino starter kits) and a few 608 bearings, I designed one for myself. Since it turned out quite good (smooth motion - not too loud), I'd like to share it with you. The assembly is pretty self-explanatory: Screw the motor into the base (cables facing downwards) using some self-tapping screws around 3-4mm (be a little bit careful with the holes since the walls are quite thin - maybe I'll rework them). I glued the Base_Ring_Cover to the base - but it will work without glue too. Insert one bearing into the center of the Table and three into the posts using three of the pins - you can glue the pins or just leave them as is - that is far from fast so they shouldn't come loose. If you need the Table_Cover_Ring, you can print it and glue it to the Table. For driving the table, you've got two choices: - Either use the Spur_Gear and the Flat_Gear: Glue the Flat_Gear onto the lower face of the Table (where the bearings are) - it should center itself around the chamfer in the middle. - Or use Wheel and Tyre (the Tyre needs to be some flexible material) for a friction drive. Why? The Gears will make more noise - the Wheel&Tyre are quite. I'm talking whispering noise levels here. What's missing: Electronics mount below the Table - I'll look into this and create a bottom for the Base which will be able to fit the Arduino, stepper driver and a battery - but I need some time to source the parts.
