Ender 3 v2 Mainboard Dual Converter 80x80x25 Silent Fan

thingiverse

This remix allows to use two converters for 12V fans (mainboard/hotend+parts cooling fan) and still requires a little refinement... But! Shows that it's possible to accommodate 2 converters, and works! Take into consideration that this is the first version, from a beginner printer, first time remixing, and first time using blender. In https://www.thingiverse.com/thing:4612023 a mainboard cover was presented, but didn't have room for two lm2596 converters. I have remixed it with https://www.thingiverse.com/thing:4684550, and enlarged the cover to fit both converters. -The small pillars for the holes of the PCBs were a little close together and need to be spaced a bit (or use pliers to adjust it). -The new walls need to be "planarized". -One converter connects to the board 24 V, and outputs 12 V to the mainboard fan and hotend fan. -The second converter connects to the parts cooling fan header (24 V), and outputs 12 V to the parts cooling fan. -The fan is a Noctua 80x80x25 fan. -Should probably use shorter wires, mine were a bit too long. For my full silent build I have used: -2 x Noctua 80x80x25 fans (motherboard+PSU) -2 x Noctua 40x40x20 fans (hotend+parts cooling) -2 x adjustable converters 24 V to 12 V -PSU cover: https://www.thingiverse.com/thing:4601320 -Silent head: https://www.thingiverse.com/thing:4223929 -Silent head support: https://www.thingiverse.com/thing:4707087 -Feet: https://www.thingiverse.com/thing:4665097 (slightly extended these to have more room)
