Graver Sharpening Jig Base Plate

This is a customizable version of the excellent sharpening jig by Jack Hobson https://www.thingiverse.com/thing:4599936

Main problem with Jack's jig is that it has been created with Fusion360, which I do not have and do not want to install. So I made a new base plate with OpenSCAD to easily change the parameters.

• You will still need the holders from Jack's version.
• I changed the screw hole diameter to 6 mm to fit a M5 insert for melting in.
• The 3 angles are printed on the back face of the jig.

There are some sanity checks in place, but please change the parameters within reason.
