This is an improved version of my previous design (www.thingiverse.com/thing:911708) Additional features are: Full access to the bed, even with the head in low position, Easy assembly/disassembly, Extended X-axis displacement. Required power to maintain the bed at a temperature of 100°C: (calculated from the duty cycle - tON/(tON+tOFF) - room temperature 22°C) Temperature measured 3cm above the bed on an object: The enclosure consists of three parts: Polyesters sheets (upper covers and shutters) of the enclosure are fixed to a support consisting of aluminum angles and plastic parts (see files), itself fixed to the X axis rods. Upper cover sheets can be lifted or easily detached to give full access to the bed
