Attachment for sharpening twist drills on a Bosch angle grinder

Thank you for supporting me!

This is another free 3D model made available for you. I love sharing my models, but designing, testing, polishing, uploading and maintaining them is a lot of work. In case you enjoy this model, please leave a small Donation or Buy me a Coffee. Thank you!

Design

The attachment presented can be slide on the protection cover of a Bosch Professional GWS 18V-7. It is one with a 125mm blade. Not sure it can be used for any other model. The point angle of the drills sharpened need to be 118 degree - which is the standard for normal drills. Sharpen only very short, the smaller the drills, the shorter. 

Printing

Designed to be printed using a 0.4mm nozzle and 0.20mm layers and PETG or PLA. Print it upside down and use organic support from the build plate only.
