This chamber takes about as little space as possible, with a footprint only slightly larger than the maximum front and back extension of the printer itself. With both outer and inner chambers in place, air temp around the print is 40-50C in an 18C basement, which is 5-10C higher than I've been able to manage otherwise. Warping is visibly reduced.You can alter some of the materials as long as the tape you use on the inner chamber is heat-resistant and the other substitutes fit. The mylar has to be thin enough to fold easily and thick enough to hold its shape once folded.
