This is a remix of the Parametric sanding block and wedge by Rmnvgr. It uses one wedge to hold both ends of the sanding strip. Makes for a tighter grip on the sanding paper. I also shortened the wedge a little bit.
The stl files are for a 7mm width sanding stick which I needed.
The scad file is also included to make your own sizes.
*updated - resized the wedge to fit better.
