Sandpaper Blocks are a percussion instrument, often used in music education. Typically they are two wooden blocks with sandpaper glued to their underside, which are rubbed together to make a sound. These STLs are for your very own pair of Sandpaper Blocks. They have a hollow resonating body to amplify the sound, which is an improvement on the traditional design, and helps them be heard in orchestral arrangements.
You will need to print two each of the body and the handle; and two each of either the abrasive surface or the blank surface (which you will have to glue sandpaper to). Provided there isn't too much warpage in the print, the assembly should be an easy press-fit, although you might want to epoxy it too for added strength and security.
These are quite loud and low pitched. You could make a higher pitched version by compression the dimensions of the files in one or more axis.
The abrasive surface STL has about half a million triangles and takes some time to slice, but it will slice eventually, you just have to be patient. If it really isn't working for you I suggest printing the blank surface instead and gluing sandpaper to it.
I printed my pair in PETG at 30% infill on a MK4S and had happy results (see photos). I did a bit of finishing afterwards with sandpaper and a buffing tool on the dremel.
Drop me a line if you print these and use them for anything, I'd love to hear about it, especially if you have any suggestions for how they could be improved.
Happy printing and happy playing!
