Holder for small PCB drill bit

Açıklama

I occasionally make some PCBs, and during the drilling stage I was wasting time taking out and putting away the drill bits.It wasn't a huge issue, but it was slowing me down a little.I finally got around to designing a PCB drill bit holder. Better late than never!It should save me a bit of time whenever I drill a board.The holder has 39 slots:6 × 0.6 mm6 × 0.8 mm3 × 1.0 mm3 × 1.2 mm3 × 1.4 mm3 × 1.5 mm3 × 1.6 mm3 × 1.8 mm3 × 2.0 mm3 × 2.5 mm3 × 3.0 mmI intentionally left out some diameters that I rarely (or never) use, such as 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, and so on.The holder was designed in OpenSCAD. The script is very straightforward and easy to understand, so feel free to modify it to suit your own needs!
