Lego hose radial fan duct mount by Warboy

Last crawled date: 3 years, 1 month ago

remixed from ZiggyRobo's design, this is altered to fit on a 40x40 radial fan, using Lego ribbed hose instead of electrical conduit - same basic thing, except it has a 7mm diameter.
i added a conical section into the insert to help focus the airflow into the tubing, and sliced the nozzle at a 33 degree angle to allow me to get it closer to the hot end without colliding with the bed/print.
as my radial fan was one that i printed, i cannot guarantee that it conforms to ISO standards in terms of the size of the opening, but the geometry of the interface piece should be simple enough that customizing the exact size needed won't pose any difficulty. it would literally be a case of moving 4 groups of vertices.
this part will have to be glued in to the fan (i used silicon adhesive) or an appropriate attachment method would need to be modelled on.
if someone has an accurate 3d model of an ISO standard 40mm blower fan i'd be more than happy to make said adjustments myself.
