Dremel(snake) PCB Drill Press

thingiverse

I loved the original Drill Press design, but it didn't quite fit my needs as-is. It was almost perfect, though - I could see myself using it all the time. The only problem was that I always use a snake-extension on my Dremel, so I decided to modify the design to accommodate that. I reworked the plans to include a special holder for the end of the snake extension. I also didn't have any spare 8mm linear bearings lying around, so I made some adjustments to the sliding base to incorporate a 3D printed IGUS-style bearing instead. This allowed me to use either a 9mm or an 8mm linear rod - whatever was easiest for me to work with. In another tweak, I ditched the 3D printed base and went back to basics. I drilled some holes in a piece of wood and hammered in the linear rods, which held fast without any movement at all. To build this modified Drill Press, you'll need: * The 8mm or 9mm Sliding Frame * The 8mm or 9mm Base Frame * The original Handle (available on Thingiverse) * Two 20mm x 3mm hex bolts and nuts * Two pieces of 8mm or 9mm linear rod * Two springs * A piece of wood for the base Some notes to keep in mind: I added a small aluminum spacer between the handle and the sliding frame to prevent wear on either part. If anything needs replacing down the line, it's likely just the handle - which is easy enough to reprint if needed. If you're interested, I've also been experimenting with 3D printing my own circuit boards using a scraper mount on my Ender3 printer. Check out my design on Thingiverse for more details.
