Enclosure upgrade

Good evening all, I am working on putting together my new shop 12ft x 20ft. I want to upgrade my enclosure and thinking of leaving the bottom open (previous full enclosure) any lessoned learned out there? Or new ideas? Open to all suggestions. Here us a few pics of what u was using.



Would like to know what others have done as far as the bottom?

That is so cool, I am trying to think how to make an enclosure like that one with my CNC machine too, I guess, I am going to try to draw the design, your does look really good.

I appreciate it, i just winged it from other designs but with a new shop dont need the shopvac underneath so was going to leave it open and trying to see pros and cons.


Thinking of my top with this base and bottom compilation.
