NEJE Laser Guard with Thumbscrew

thingiverse

After reading hundreds of post about building huge enclosures for lasers I decided that the only thing I really needed was to enclose was the laser light, not the whole machine. This is printed on a SLA printer with clear resin utilizing 5 drops per vat of orange alcohol ink. After mixing it produces a print that blocks about 90% of the light emitted by a NEJE 20w laser. This was verified with a spectrometer.
