thingiverse

You'll be inspired by STL files, but don't expect a perfect fit due to variable screwdriver accuracy. The design comprises three separate parts - one for the lower cover, one that uses elasticity to hold everything together, and one for the upper cover which incorporates the switch mechanism. For a drill press stand, consider this setup from Wolfcraft http://www.wolfcraft.com/en/products/p/drill_stands/1_drill_stand-1/s/p/index.html
