Laser lens holder for 2 lenses
thingiverse
This is a laser head nozzle basicly made by Russ "RDWorks Learning Lab 139 Designing a Compound Lens System" (thanks Russ!). https://www.youtube.com/watch?v=sp2O6komevw&t=796s You need to fit an o-ring inside to make it sit properly to your lens tube. Watch the video for more information about the choice of lenses etc. EDIT: I noticed a small spot at the lense nearest the bed. I use GaAs lenses AND a very little power. Keep that in mind!
