K40 Laser calibration tool 2
I decided to build the K40 Laser Calibration Tool to rough-in the alignment of my CO2 Laser after replacing all of the mirrors and optics, but the little red lasers I got were 6mm instead of 7mm. So I threw together a rework, using OpenSCAD, so that I could customize the laser diameter and make it a press fit.
I'm sharing it here in case anyone wants the OpenSCAD file to do further customizations without having to start from scratch.
