Mini Drill Press for PCB Drill - Dremel version

All Credits to http://www.thingiverse.com/thing:628696 for this awesome design!

I added brackets for a Dremel-like tool and changed the Gear with a nut inside, so adding one nut on each side of it (3 more M6 nuts in total) will make it really strong, my problem was the weight of the tool was already too much to handle for the original gear.

Also added 2 springs cause of the same weight problem.

Thanks again for design!
