20 to 1 Reduction Gear for the Bambu TT Motor

This is a 20:1 speed reducer for the Bambu TT motor.  It reduces the speed from 59 RPM to between 2.5-2.75 RPM. It also increases the torque.

The gear box can be configured for a right-side output or a left-side output.  It can also be adapted to create a vertical output. The STL can be incorporated into your own designs for a reliable gearbox.

There are two options for output configuration.  There is one shaft that mimics the shape of the output shaft of the TT Motor.  There is a second option with has a larger square drive connection point that will be stronger. The square output connector measures 8mm x 8mm x 8mm.

It utilizes 4 self tapping screws (BT3 x 12).  A slightly shorter 10mm screw would also work.
