Sharpener for ski waxing scrapers similar to the small Toko one. It has 3, 4, 5 and 7-mm slots for different thicknesses of scrapers.

You will need a plane blade as the sharpening tool. I used a Rali 48mm blade that I could find in a local hardware store (see photo). If you find a different blade, you will need to adapt the design; however, it should be relatively simple from the FreeCAD source.

To use, insert the scraper in the appropriate slot and let the tool run along its length.

See below for printing and assembly instructions.

Print on the edge in order to correctly create the slit to insert the blade. The design contains thin support structures you need to properly print the slots.

I suggest using a brim to improve adhesion, high infill, and a resistant material like ABS. PETG could also be acceptable.

Once finished printing, remove the support structures (the thin walls that close the holes) with pliers and carefully introduce the blade into the side slit. Be careful to use pliers and not to cut yourself while doing this!

Once the blade is inserted, push it down into its final position.
