Turntable Bevel Gear

Unnecessary but necessary. I had a SG90 servo but no resistors  to make it turn continuously. I had some leftover motor from an other project, so I decided to change the spur gears to bevel gears. I further changed the base because the motor is a bit bigger and I could not fit in vertically.  

Original Part from 3D_Goblin:

Motor is L149.12.392 from Micromotors.

I also change the big spur gear ring with the intention to add some heat insert, because else the print would be a painful one. Added some spacer and voila bevel Gear Turntable.

Because smooth operation does not matter, the rollers will be printed with a resin printer. 

FYI:

The tolerances of the bevel gear are very precise (made in Inventor - tolerance are normally for metal produced parts) and surely not suitable for 3D printed parts so one must probably scale the smaller bevel gear down.

ATM its not tested.

Update - 05.05.2023:

Design did totally not work, not at all. Obviously the bevel gear added some force diagonally and pushed the beveled gear ring away, this lead to total halt of the mechanism. 

I added a center rod holder for a 8 mm shaft, that keeps everything coaxial. Further constructed some adapter, that I must not reprint everything. 

I didn't had a 8 mm rod, so for testing purpose I used a 8mm drill.

Update 2 - 05.05.2023 (grammar update 19.05.2023) :

Added the Bevel_Gear_21 with the already 8mm hole in it, so no weird adapter is needed. 

Update 3 - 19.05.2023

The bevel gear 21 has now a dedicated spot for a 608 bearing and the centering supporter is a little bigger in diameter so it will grip better and thus centers the 8 mm rod much better. The motor now runs much better and uses less amps (before max 0.04 - now 0.01 amps)

After a short test it looks the bevel gear21 is a little too big and scratches on the cover. But in general - it does work ;-)
