Turntable

Modular, motor-driven presentation board based on the worm gear of the original model

3D scan turning table by Rogue_72

One model (motorbase single) is designed for operation with only one platform

The end module can also be plugged directly into the motor base modularly

Two turntable sizes are available: D146mm - mounted on every second gear 

D70mm (for miniature figures) - can be mounted on any gear

Required parts:

DC Power Supply 

Switch and possibly DC Jack 

M5 Heat Set Inserts (I use the ones from Ruthex) 

M5x10 Screws 

1 x M3 Heat Set Insert  

7 x M3x8 Screws (for the motor and axle)

Assembly: 

Print the base parts (for example, I used 1x modular motor base + 2 extension modules + 1x end module) - total length in this case approximately 850mm. It may be possible to make it even longer, but I haven't tested it.

Print the required quantity of gears, bearings and 1 worm

Insert the heat set inserts (M5 in the bearings and platforms, 1x M3 in the worm)

Mount the motor and worm to the motor base

Now you can screw the bearings onto the panels from below through the slot and insert the gears. 

The gears should not be too close to each other to avoid creating stress in the gear system.

Tips:

 A little Prusa lubricant on the worm and gears, and possibly in the plain bearings, makes everything run more smoothly :) 

By reversing the motor's polarity, you can change the direction of rotation – I polarized it so that the worm engages the gear in a downward motion.

Happy printing!
