5 inch disc sanding holder for lathe chuck

thingiverse

This is a 5" orbital sand paper holder that I designed to clamp into my wood lathe. A 4 jaw chuck bites down onto this and holds it stable for sanding. I just used monoprice pla and it has ground everything form steel to 3d parts with ease, I thought heat would be an issue but its holding round perfectly. I use wood glue to adhere new paper and a chisel to remove worn down paper. I am using a wooden box that I made as the sanding surface in order to get nice 90 degree sanding angles. Always wear proper safety gear when working with fast rotating parts! BTW my output file does not contain facets, I am not sure why the preview is showing a faceted object. It should be perfectly round.
