Bambu Lab bracket for Noctua fan 40x20

thingiverse

This bracket/mount allows you to replace the stock 40x10 5V Control Board Fan with a Noctua 40x20 5V fan. https://noctua.at/en/products/fan/nf-a4x20-5v-pwm This fan size allows it to fit nicely without getting in the way of too many wires, while pushing more air and being more quiet than the stock fan. This bracket positions the fan right in front of the control board's heat sink, thus performing the exact same function as the stock fan. The bracket has counter-sunk closed holes using just a single layer: this allows to print the hole's small overhang without needing any support and is easier to clean up. I used the rubber NA-AV3 anti-vibration mounts provided with the fan to attach it to the bracket, however, you could also use screws instead. More information about how to replace the stock fan available on this Bambu Lab forum: https://forum.bambulab.com/t/noisy-mc-board-fan-and-possible-fix/2716/19 Material: ABS, ASA or any high temp material you prefer (do NOT use any PLA blend). Supports: no Walls: 2 @ 0.4mm nozzle Layer height: 0.2mm Infill: 10% Sketchup .skp file provided if you want to remix it.
