Improved lack enclosure with dry box ptfe tube connections and other upgrades

I wanted a ikea lack enclosure that had filament fed into it via ptfe tubes coming out of dryboxes.

I really like a lot of things about the original prusa lack enclosure but wanted a few changes.

For example, my printer is on a muscle rack shelving unit bolted to the wall. It is much sturdier than a couple of lightweight lack tables stacked vertically so I don't need the bottom table as a stand.

The legs of the table are connected to the shelf with a steel plate on top for fire safet
