LED Ring - Laser Position Indicator

This video shows a bracket used to hold a ring of LEDs intended to produce a visual indication of the position of a CO2 laser focusing lens. I install the bracket onto a K40 CO2 laser cutter in the video. I have uploaded the bracket to Thingiverse, Here is a link: https://www.thingiverse.com/thing:272... The bracket and LED technique was inspired by Peter Jensen's video on the 4 Dot Laser Position Indicator. He even offers a kit version (at the end of the video linked below an e-mail address is provided).    • 4 dot laser cutter position  indicator
