Drill press laser centre

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:

I have included Fusion 360 f3d and step files to allow you to modify if necessary.
