Zesty Nimble Motor Gimbal

thingiverse

I designed a swivel mount for the extruder stepper motor from scratch. Initially, I was going to secure it to the tower using a single long screw passing through the axis of the bearings, but I couldn't find a long enough screw in stock and had to modify the base instead. As a result, you can probably skip the central screw altogether and print the axis without any holes. To prevent excessive movement when adjusting the head's position, I added a limiter mechanism. The axis features two 608 bearings stacked one after another, with a gasket of 0.5-1 mm thickness sandwiched between them.
