I needed an angle guide for sharpening bigger drill bits on my bench grinder. With this I can move the bit on the grinder table from side to side and tilt it around the table edge. For now I have added only 118 degree tip angle files. Printed from PLA with brim, rotated 90 degrees around the X axis. The wedge can be temporarily attached (by double sided tape) under the base to maintain the secondary angle.
Included FreeCAD source file. You can enter the drill bit diameter in Spreadsheet for example “=13.5 mm” or "=0.375 in" and export the part to stl file.
