Ice skate sharpening jig

My grandkids are getting into ice skating and the blades on used skates are often dinged up. Skates can be manually filed, but you need a jig to keep the file centered properly. This jig does that. It is for a 10" half round file such as you would get at the hardware store. I used a single cut file but a double cut would work as well if the skates are in rough shape.
I have used the Fusion360 file in case you need to modify for a different curvature of the file (this one had about a 1/2" or 13 mm radius).
I generally use Overture PLA PRO for jigs and fixtures.
Hardware openings are sized for M5.
