Drill press laser centre

thingiverse

A remix of original by dmerand that allows better adjustment of laser diode in two directions. This is my first iteration so is a bit larger than I would have liked, but it works perfectly. It is designed to fit a 42mm diameter chuck. I printed the laser holder with supports, but the body parts without. Assemble using 3mm screws. The laser holder takes two LR44 button batteries which are connected via wires I melted into the plastic. The switch was something I had kept from some old electronics I salvaged any usable parts from. There is a hole to poke out the batteries when they need changing. 5V Diodes are available from a range of suppliers or ebay: https://www.ebay.com.au/itm/5V-Laser-Module-Red-Dot-650nm-5mW-Laser-Pointer-Laser-Diode-5pcs/172264903779?hash=item281bc9d463:g:G94AAOSweWVXfHRe I have included Fusion 360 f3d and step files to allow you to modify if necessary.

There are 1/4" screw holes at the rear (opposite the laser holder) where you can screw in grub screws to assist in dynamic balancing to further reduce vibration.
