BCN3D Sigma enclosure

Enclosure for my Sigma. It's main purpose is to keep hot air around the object during prints to reduce warping.
It consists of three parts: Outer shell is 4mm thick bent SAN plastic sheet with printed clamps and hinges. The door is removable and stays closed small levers. Inside the printer is a U-shaped shroud around the heated bed that attaches with magnets to the extruder motors.
With the enclosure I can get the internal air temperature to around 65°C and it also makes the printer a bit more quiet.
