A20M ring air duct

thingiverse

This is an A20M fan duct with a slightly offset ring opening that's still fully functional. Despite its compact design, it provides an unobstructed view of the printed object, allowing for precise monitoring during the printing process. To ensure optimal results, position the duct with the ring facing upwards. Conveniently, built-in supports are integrated into the inlet and can be effortlessly removed using specialized support clippers.
