BCN3D Sigma enclosure

Here is a rewritten version of the text in American English, free from foreign characters, with an active voice tone and a Flesch-Kincaid grade level of 100%: "I'm designing an enclosure for my Sigma that keeps hot air circulating around the object during prints to prevent warping. The main components include a sturdy outer shell made from 4mm thick bent SAN plastic sheets, reinforced with printed clamps and hinges. This shell is designed to be removable and stays shut with small levers. Inside the printer, a U-shaped shroud surrounds the heated bed, secured in place by magnets attached to the extruder motors. With this enclosure, I can achieve an internal air temperature of around 65°C and also reduce noise levels significantly."
