Functional Differential Gear System

The smaller gears were initially difficult to print due to overhang issues. OpenSCAD was utilized to fill the bottom of each gear's hole, creating a clean bridge for printing. The hole remained partially intact to serve as a drilling guide. OpenSCAD's import feature allows for easy modifications using an STL file. To complete the process, print the v2 gears and use a 3mm drill (preferably in a pin vice) to finish cleaning out the holes.
