Laser Focus Ring

These are replacement focus rings for the HPC LS1290 PRO Laser

We had a *minor* fire on our laser bed which melted the white focus ring attached to the lens. As we have gone through all the rings provided by the manufacturer, I made up this file to cut a load from some 0.8mm HIPS.

I used a low power, x3 passes, and put mdf underneath to prevent the plastic from melting and dropping (this didn't happen).
