Nice install.
I have to say that going by the photos, the plastic you used for the enclosure sure looks thicker than 0.010" (unless you laminated 2 or 3 thicknesses of it). 0.010" sheet styrene is very flimsy.
It does look thicker in the photo but I double-checked the Evergreen packaging which says 0.010" I also mic'd it and it measured 0.011."
I didn't laminate it. I did this more as a curiosity to see if the flimsy 0.010" would assemble into a decent enclosure. It is harder to work with in assembly than 0.020" for sure.
Besides having it on hand (I couldn't find any thicker plastic in my box), I used it since I didn't want to have to do any shell thinning for width. I already have one FVM GEVO shell in my "Kill" credits because of my ham-fisted efforts to thin its shell.
