A guide that is a carriege on wheels and helps to maintain your knife angle. This version is designed for sharpening blocks ~26.2 mm high and ~56.5mm wide. You can change the size in the STL file, but you may to have to change wheel sizes too.

The model is composed from:

• the carriege propper (carriege.stl)
• wheels (W1.stl) 4x
• axles for the wheels (B1.stl) 4x

The axles are intentionally a tight fit into the carriege. Heat up the carriege before inserting them.
