A1 Fan Riser for Enclosed Printers

Update 21 Dec 2024: added front and rear extensions to the blower riser. These extensions fit nicely into cutouts on the printer and stop it from shifting front to back and side to side. Also added TPU pads for the underside of the riser, just gives it a bit better traction instead of flat PLA on the enclosure’s aluminum interior. I run my A1 in an enclosure since my printing environment is not ideal (humid and cool basement). The only problem is Bambu Lab didn't put any cooling inside the A1 and they recommend not running it in an enclosure for this reason. So, I made these risers to inject air from beneath directly on to the electronics. I dont think this causes enough air flow within the enclosure to affect the ambient air for printing. I initially made the fan riser version, but found the air flow was pretty restricted. Turns out fans are better for moving large volumes of air in unobstructed paths, and the air path here is fairly obstructed. For this reason, I also made a blow
