About this 3D model

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.
