I meant to post this awhile back but better late then never.
Here’s a post of what my enclosure looked like when I first built it. Since then I’ve added a door in the back for pass through work. Anyway my main reason for posting this is because I’ve never regretted making my enclosure super tall. I’m 6’2" and don’t like hitting my head! It’s also made the vac and laser exhaust hose management a breeze, they just come through the roof near the center. I don’t use FB so I can’t see how @mbelleri’s design is for access.
Good luck with your build! I wish I made a torsion box because I get some movement with humidity changes with my plywood and 2x4 base.
