After several tests, I found that to improve the relief angle, you have to bring the pivot point as close as possible to the sharpening stone.
Then I modeled an improved version (V2).
Be careful not to burn the material because the drill is very close and heats up quickly.

This is a remix from MGX tool.
When you turn the drill to give it the relief angle, you should push it slightly upwards
A drill holder with smaller slot was added for little drills. (I have thick fingers and I could not hold them)
Needs to add:
M3x8 allen bolt
M3 nut.
