K40 Laser Engraver Mirror Alignment Plug

This is a simple holder for a mini 6mm laser diode module that fits into the tube of a K40/equivalent CO2 laser engraver/cutter.

There are channels on the side for the laser module wires to exit the tube to connect to a battery.

There is a flange to prevent the plug from going too far into the tube and to lie flush against the tube to ensure the laser is centered.

This is my first Thing. Please tell me if I'm doing something wrong/ignorant. Do not hesitate to educate/correct me. I'm here to learn!

Infill:

100%

Notes:

100% Infill may be overkill but I did not want the flange to break away which would make removing the plug more difficult. I also didn't want any flex in the walls which would alter the laser module's trajectory

How I Designed This

When I was aligning the mirrors for the first time, I burned my hand twice as I was getting impatient. I figured there had to be a better, smarter way of doing this. Instead of checking alignment with a test fire of the laser every time I fiddled with the mirror(s), I mocked up this laser module holder so I could get real-time feedback from my mirror adjustments. There are channels on either side of the plug for the laser module wires to connect to a 3V battery.

SAFETY

Obviously, REMOVE THIS PLUG BEFORE USING THE LASER. In fact, I would suggest unplugging the laser engraver completely while using this plug. I am not responsible for damage to your laser and/or bodily injury. As always, BE SMART AND VIGILANT WHEN IT COMES TO SAFETY - especially with dangerous equipment like these engravers. If you do not have one yet, buy and keep a fire extinguisher to dedicate for a device like this!
