Stepper Motor Driver Case with snap-on lid

This case fits an inexpensive stepper driver + controller that is available at Amazon. The case was printed using an X1C with AMS and PLA filament. All print settings were the Bambu Slicer defaults for Bambu PLA Basic. No supports were used and the brims for the two push buttons were automatically added by the Bambu Slicer. Included are the Bambu Slicer project file, STLs, and CAD STEP files if you want to make changes.  Assembly is straight forward:

1. Print the parts
2. Install the 2 ea. M4 heatset inserts into the TM6000 base 
3. Slide the TM6600 printed base onto the case bottom
4. Mount the stepper controller board using 4 ea. M3 screws
5. Add the SPEED control knob + nut + washer
6. Install the power jack and power On-Off switch
7. Use the electrical schematic to add the wiring 
8. Place the printed push buttons onto the stepper controller board push buttons
9. Snap the case top into position

Please note that the electrical schematic was extracted from one of the Amazon reviewers comments and has worked with the stepper controller board that I received. Unfortunately no schematic is provided with the stepper controller board.
