About this 3D model

I have an 8" CBN (Carbon Boron Nitride) wheel on my bench grinder, and I needed an accurate angle guide for my woodworking chisels. This guide has 4 different angles: 17º, 20º, 25º, 30º The ends of the guide are purposefully shaped so they conform snugly to the 8" diameter of the wheel. Normal grinding wheels wear with use, reducing their diameter, but CBN wheels don't (well, practically speaking), so the guide should always conform to the wheel. This helps to set the angle more accurately. I printed mine in PETG-CF, and the included print profile is for that filament, but just about any filament will work. Tweak the setting to match your filament.
