Precision drill press for PCB
thingiverse
Hi everyone! This model requires more metalworking than others, but it offers fantastic precision and durability. The knob can be obtained from this design https://www.thingiverse.com/thing:144333. A 10mm LED is used, and a resistor must be calculated based on your specific setup; I'm using an 18650 battery with a DCDC Step-UP and two 470R resistors. The motor comes from an Epson inkjet printer. To get the rods, you'll need 6mm and 8mm ones. Update: A fan is installed on a China-made 3.175 drill bit colored belt. Update: The CDR lasercut box is included.
