That is nice idea!!! Thanks! But also could be troublesome.... I could not open it while printing and considering my attention spam I would do that for sure LOL
The top lid, in the end, is optional - the main printer is just a cube with the lateral extrusions. Anything extra you can do at your taste.
In this case I would like to have a glass/transparent/fake mirror (mirror to inside) front door. Removable lateral panels for easy maintenance. With some thermal insulation inside to have a true heat chamber :D
But can be a naked cube like my current Hypercube Evolution and it will work nicely!
