This turntable is designed for a Futaba FP-S148 Servo modified for 360 degree rotation. You will also need four 13.5mm ball bearings and M3 hardware for mounting. There are numerous mounting holes on both the bottom and top of the turntable, so attaching parts to it should be straightforward. All parts are printed in .2mm resolution with no supports. I have included the Fusion 360 assembly file as well if you'd like to modify the design for a specific project. 

Enjoy!
