The file '210x70x30 Whetstone Sharpening Helper 3D Printer Model' is (f3d,stl) file type, size is 935.6KB.
My whetstone is too big for Rejd's sharpening guide, so I increased the size and divided it into parts that fit diagonally on an Ender 3 style (220x220 mm) printer. I had to disable "Skirt" and print one part at a time.
I've included my Fusion 360 files, but they are a bit hacky because I started from Rejd's step files and chopped them up.
