In spite of enduring the second hip replacement in one year I managed to get some work done on MoBeam. 
Two changes:
- New head mounting with optical shielding. Compatible with G8 & G2 lens focal lengths
- Alternate to honeycomb bed
I redesigned the head mounting and added optical shielding.

Alternate to honeycomb bed
I found out that my honeycomb is not very flat so I looked for an cheap alternative.
Turns out 3/4 angle aluminum was exactly the right height when laid on the adjustable focal frame with its edge up.
So now the adjustable focal frame can have a solid material (engraving) or these movable struts for cutting. I probably will anodize all the Al parts black.
