This is a housing I designed to hold together the cooling parts (Peltier coolers, aluminum water blocks) and form the base of a cloud chamber for viewing radioactive particles. There are two parts, the thinner top piece is separate so it can be finely adjusted in height to make sure the other parts fit snugly. There are holes to accommodate brass threaded inserts which should be heat pressed into place after printing. Printed in PLA 0.30 mm layers.
