Adapter nut for diesel air heater

thingiverse

A couple of years ago, I purchased an autonomous Hcalory diesel heater for heating the garage (China). Initially, the device is designed as portable equipment. Air Intake Adapter Nut for Chinese Diesel Autonomous Heater, Image No. 1 But, due to problems with heating in the rented room, we had to move the heater there. The room temperature of +13C does not contribute to normal 3D printing, especially with photopolymers. It's much better with the heater. Then the question arose of the organization of supply and exhaust ventilation, because printing with photopolymers is associated with the use of solvents, which is not pleasant to the nose, and not useful for breathing. The air intake port on the heater is closed with a lid, which is the locking nut of the heater housing cover for one thing. The lid has an outer diameter of 85 mm. This size is not compatible with the internal diameters of standard ducts (100 mm, 125 mm, etc.). Therefore, I modeled an adapter nut with a transition of 100 mm.
