Drilling Bounding Ring

When I needed a depth limiter for the drill, I downloaded models from other authors. These are interesting models with a collet lock. But in fact, they were useless, because the fixation on the drill was insufficient and the limiters simply slipped, especially when working with the hammer drill. So I created my own drilling depth limiter design.
I made three of the most popular diameters for drilling with a hammer drill 6-8-10mm. However, you can use the source file to modify it for yourself.
The model is printed without support, print in place.
To complete it, you will need: M4x12mm Hexagon Socket Screw and M4x7x2 Square Nut.
