Neat design. I like the 'stance' it has. We ran into a similar problem laser cutting thicker plexi. It retains heat long enough to melt the seam back together in the tighter cuts.
The water bottle full of solvent bugs me. I was instantly reminded of the "The Young Ones" episode with the homicidal maniac potion in a Coke can.
"I just
