Beskrivelse

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. See the printing instructions in the print profile. Boost Me (for free) If you like my models, please give them a boost!
