parametric sanding block sandpaper holder

cults3d

A customizable sanding block designed to economize by not requiring much extra length of sandpaper to wrap around and clamp in place. Default dimensions are small, but you can make it whatever size you like. You can also customize the end angles. The clamping pieces are printed inside, in close enough proximity that they don't tip over during printing, and probably stick lightly to the inside of the block. I was able to pry them off easily with a screwdriver afterwards. Vitamins required: 2 M5 bolts (around 1.5-2cm long) and 2 M5 square nuts. Wing bolts might be nice if you have them, otherwise you'll need a screwdriver to install the sandpaper. Or use hex-head bolts and print out a pair of knurled knobs (http://www.thingiverse.com/thing:439239). If you want to make a soft pad on the bottom, you can use some self-adhesive felt or cork, or glue on a piece of denim from old jeans.
