I couldn't find a slatwall hook to hang my round wood rasp, so here is a 3D print. There are two parts, the slatwall hook and the tool holder. The tool holder requires supports. Once printed, add some superglue and put the two parts together.
I have ProSlat slatwalls in my shop, so I know it works for this brand. Note that the gcode files are for 0.6 mm nozzle, so reslice if you have a different size. OpenScad files are included if you need a different size.
