TL,DR: Get good high static pressure radial fans and well-designed ducts for part cooling

Initially I was running a 40mm x 20mm axial fan capable of supposedly higher static pressures than typical axial fans, but overhang and bridging performance wasn’t spectacular, partly due to the fan as well as the duct design. I recently replaced that with a 3.5W radial blower fan with a new duct design that directed the air right at the base of the nozzle, and that increased overhang and bridging performance tremendously. In fact, you can almost see the relieved “3DBenchy” text on the back plate of the boat.

Seriously impressive setup and print

@Alex_Skoruppa , I can publish the design; the entire machine is basically “finalized” (nothing is ever finalized haha) so I’ll be posting the documentation for the entire machine pretty soon hopefully!

@Alex_Skoruppa , here is the file for the fan duct if you want to take a peek at it before I get a chance to publish the rest of the machine: https://grabcad.com/library/sample-5015-blower-fan-duct-3d-printer-1
