775 Sanding Machine

An upgraded version has been released, check it out: Desktop Mini Bench Grinder

1.The motor opening is only suitable for 7-series DC motors, such as the 775 motor.

2.The motor requires two M4 screws for fixation.

3.All other fixing screws use M2*6 or slightly longer self-tapping screws.

4.Other materials: A DC motor speed controller is needed for motor speed regulation, and a DC-099 DC female connector 5.5x2.1 for power input. Use double-sided adhesive magic stickers and 4-inch flocked sandpaper for the sanding disc.

5.Dustproof mesh can be added to the hollow parts of the model; I used cheap and effective chassis dustproof mesh.

I used a short D-shaft 775 motor removed from a fascia gun. If using a conventional round-shaft 775 motor, separate top cover, dust cover, and sanding disc components are included in the model files. Additionally, for round shafts, you'll need a 5MM inner diameter flange coupling, four M3*8*4.2 knurled nuts, and four standard M3 screws to secure the sanding disc and motor shaft.
