This is my miniature Drill press.
I made it to drill holes in PCBs.
The brackets have a inside diameter of 24mm.
Be free to read the instructions :)
Inspired by this project on Thingiverse
(mine is a total redesign)
Drill is from Ebay here
Sadly, the drill chuck could be better.
6x M3 Nut
About 320mm M6 threaded rod (70mm + 2*125mm)
4x M6 nut
2x M6 washer
wooden base 125x60x18mm
24mm diameter drill Motor (Ebay)
Be sure the parts are completely cool, because if they are hot, they will shrink a bit.
Rasp the slider crosswise on a sheet of sandpaper until it fits the base perfectly. The sandpaper should lie on a flat surface. I only sanded the surface width the gear rack.
I attached the gear width superglue to the threaded rod. Same thing width the lever.
