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