3D Printing

I was giving some ideas to @shauki and came up with the idea that regardless of if a delta style 3D printer is full enclosure friendly, the bottom area of the printer will never have the mounts for the diagonal arms reach those positions so you could have a smaller wall up to that height. The back two walls could be wood or printed and the front wall, if you have one, could be clear so you can see the print. Anyone have any opinions on this?

I know what you mean but wats the purpose of that and stability is a concern

A wall prevents draft. If it is at least 3 inches tall, it will help avoid things popping off the bed.
What stability concern? You are adding material, not removing it.
