Kossel Layer Fan Duct and Mount E3D by zethyl

Last crawled date: 3 years ago

Layer / part fan mount and duct for your Ultibots K250 BSE (and likely other derivatives).
I couldnt find a fan duct and mount solution that worked for me. Common issues were: restricted XY travel limits, poor performance, or just plain flimsy. Whats an engineer do in that situation? He designs his own. Mine is by no means perfect. I know there are issues with the angles but if printed in PC it wont get soft and will stay rigid.
Designed for a standard 5015 centrifugal fan to mount to the Ultibots mag ball efector. I recommend printing in polycarbonate for the temperature resistance. If you print in something else put some kapton between heater block and duct for insulation.
I uploaded the native Creo .prt so feel free to modify to your needs. I also included a STEP and STL. Walls on the duct (k250_annularfan & k250_annularfan_cs1.stl) are 0.5mm thick, print with a 0.5mm nozzle. I suggest keeping those equal to ensure you get a good single wall so modify CAD to your nozzle size or get a 0.5mm nozzle. I do not plan to make any updates at this time.
