Corded mod housing for Dremel 7700

It's built to accommodate m2 bolts into m2 heat-insert nuts fitted in the top section, requiring 6 m2x6 bolts for the casing and an additional m2x4 plus a washer to hold the circuit firmly in place. For the display, 2 small screws are sufficient. To assemble the clips, two 20mm rods and some springs are necessary (I utilized the springs from small alligator clips). The thumbwheel requires a small 2mm rod of approximately 6mm in length to spin on and a thin sheet of metal or plastic to engage the potentiometer; however, this component is not included in the model as it would be too fragile.

Assemble at your own risk.
