Palm Sander

cults3d

This palm sander utilizes RS-550 motors with the metal sleeve around the motor. If you don't have RS-550 motor, this can be used as is as well. The concept of this design is to make it easy to size up the sandpaper without requiring extra tools such as knives/scissors and cutting them up to sizes, unless you want them to have clean edges. This design of mine eliminates the need of special non-3d printed clamp to hold the sandpaper in place firmly Sandpaper size for this palm sander You fold 3-4 times of that sandpaper sheet, and tear it off from the crease slowly. About the stl files The main body, has 2 variants, one with sponge attached to the flat side of this with roughly 5mm thickness, and another without sponge, you don't have to resize your sandpaper if you want to swap to either one; sponged or no sponge type. There's a folder that "please adjust xy offset", adjust the xy offset accordingly. By default these parts has about 0.05-0.10mm tolerance uniformly, to avoid wastage, just add another offset around -0.10mm. Enable fuzzy skin for the fastener for better grip on tightening. Mounting the motor You going to need to print ballast, motor mount and motor cover optionally. 2 M3 x 6 or 8mm screws are required and make sure the stator inside can spin freely without being jammed by the screw. Add washers if needed. Or even better, use spring washers. Ballast uses M3 nuts as weights Screw the motor along the motor mount into the main body, make sure the motor are tight in there else disaster may strike. Motor cover part are optional, but better just to put them on as the motor can get hot, it also can retain the motor from becoming loose overtime.
