I needed a rotating table for a while 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 came 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 liitle 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 1 Bearing into the center of the Table and 3 into the posts using 3 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 bearing 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.
Non of the Parts needs support and has to be flat onto the print surface. I´m unsure if the parts are in the correct orientation.
Use enough top/bottom layers to make the surface (especially the Table) nice, even and non translucent.
I will finish the table with primer and white paint to smooth it out and make it non see thru (you can see the infill and the red base under good lighting for camera / filming setup.
If everything is printed in a non translucent white with enough top and bottom layers no finishing should be required.
