Here's a drillbit sharpener I've made long ago. I got my inspiration from "mgx" who built a drillbit sharpener for a dremel. So here is one for the Proxxon IBS/E.

You'll also need:

• 1x screw M3 x 30 mm (hexagonal will fitt well, for fast assemble/disassemble)
• 1x nut M3
• edding or similar (to paint the marks)

I appreciate any Feedback on my posts, thanks! :)
