Gearbox

A reupload of Fortzero's design on Thingiverse.

The “Original Files” folder contains the original files available on Thingiverse.

In addition, I've uploaded a Fusion 360 file you can use to customize the holes for the motor, as well as an exported STEP file that uses the modified hole dimensions I needed for my motor.

The editable parameters are:

• MotorGearHoleSize - the size of the hole for the motor
• MotorScrewHoleSize - the size of the two screw holes for the motor
• ScrewHoleDistance - the distance between the centers of the two screw holes

The four screw hole sizes for the lid are not currently customizable, they have the original size of 2 mm, which is intended to be tapped for an M2.5 screw. M2.5x8 screws are recommended.

The exported STEP model uses values of 2 mm for the motor screws as well (meaning they also need to be tapped for M2.5 screws), the motor hole size is 6mm, and the screw hole distance is 14 mm.

All of the original gears should work with this modified case. See the the original Thingiverse details for assembly instructions.
