rectangular drill adapter (MagFloat aquarium glass cleaner)
by summetj, published
This adapter allows you to use a drill to rotate a MagFloat aquarium glass cleaner. (Or any rectangular object, if you edit the openscad file...)
Print it. Drill out the hole using a 3mm or 1/8" bit. Insert an M3 Hex Head screw. (I used a 35mm long one). Use a M3 washer and nut to hold the screw in. Grab the screw with your drill's chuck. Place the adapter over the outside half of a mag-float aquarium glass cleaner, and power away!
Edit the openscad file to generate a drill adapter for any rectangular object.
