K-40_Lens_Alignment_Kit

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/kPun6VupbdR

The following thing is used to help align the laser mirrors and the cap goes on the laser tube so that it shoots in the same path.
This helps significantly with alignment... i have 4 perfect pin-hole shots after using this apparatus.
The laser diode is 6mm wide to fit the cap...
