Description
This is part of a larger project I'm working on, but I thought someone else might find it useful elsewhere.
It's an adjustable mount for gripping a drill head, pen, or whatever else you can come up with. The exact position of the head within the mount can be adjusted with the 4 grip screws. There are also a load of mounting holes for various configurations.
The file is fully parametric. The STL is set up for a 2cm hole, with M3 screws.

I've got a low-rider setup in place, so I don't think that will fit. It'll be a easy enough to throw together a compatible mount. 1 step at a time though :)
Sounds interesting.
Did you try http://www.thingiverse.com/thi...
or what are you using for mounting the PCB?
The aim is pcb drilling. I've already got a fully photo exposure etching setup, just need a way to make the holes. So only up/down but needs to be at speed with a small bit.
The setup it's self is using 2 of these about 50mm apart. The screws allow me to get the bit perfectly perpendicular to the board surface. Once it's finished, the whole lot will be articulated with a servo for rapid up down motion.

Grip-screws cannot withstand a lot of shaking.
(I considered them but gripped a Dremel flex shaft along all of it's length instead
in my tried and working toolhead.

If you keep them, I suggest 3 instead of 4.
That should make it more practical.
3 screws messes with the alignment of the rest of the device (got the 3 screw version sat printed in front of me right now). The reason I'm using this one is to allow very fine control of the alignment. When you start drilling 1 mill holes at any speed, alignment becomes critical.
As for shaking, it wont be as serious an issue as you think. I've tested the head, and other than when spinning up and down, it's remarkably stable. Admittedly it's not a real dremel, just a clone. Worse comes to worst, a drop of thread lock will stop it moving.
