Integrated Dremel Mount for Zen Toolworks CNC

Instead of bolting the tool holder to the base plate I decided to integrate Batchkrazy's design directly into my (100mmx70mm plate size) to get additional clearance in the y direction.

- Used FreeCAD 0.17 to import wire mesh or STL
- Converted it to a solid object
- Elongated it a bit to match my base plate
- Merged my Zen toolworks baseplate FreeCAD object with pre-drilled holes onto it
- Fused and refined the result object
- Exported it back as a STL file
- Added FreeCAD file
