A few snaps from my weekend project with MoI 5 - replacing my noisy Amazon ducted inline fan unit with a custom, low-noise version using a standard 140mm PC fan.
Mounts magnetically (10x2mm magnets), print time ~6 hours for the largest part using PET-GF15. Used to distribute cold air from the only room with aircon into others using 100mm OD flex ducting.
