Jointer Sharpening jig

Holds 2 Blades at a time at a user specified angle.  Uses 6 M3x12 Button or Socket head screws and M3 nuts for assembly.  I include multiple versions at different angles to cover most common cases.  

Print Settings:  PETG, 5 Walls 5 Top and Bottom layers. 15% infill gyroid. (I used a textured plate and did not need a brim or mouse ears for this to stick)

Print Orientation: Print standing tall (vertically)

Personally i printed 2 for use.  My Knives were at 40 degrees so i printed a 40 and a 42 degree version.  When my knives need a significant regrind i use the 40, and then finish them with the 42 to get a micro bevel and make touching them up much faster in the future.  If you have an odd number of jointer knives just rotate through them swapping one out at a time, you can count the number of swipes over the sand paper you do and make sure all 3 get the same number of strokes.  

For instance.  Blade 1 and 2 in the jig 10 strokes, take out 1 insert 3, 10 strokes. Take out 2 insert 1, 10 strokes. Now all have been ground the same amount.
