Makergear M2 Larger Electronics Box with 2 LM2596 Holders

thingiverse

I've converted all the fans on my printer to 12v Noctua fans for lower noise levels. Since the Printer pushes 24volts, I needed two LM2596 Buck converters to convert the output to 12v. I also added active cooling fans to the X, Y, and Extruder motors and installed LED lights as well. I built a distribution block with two sides, one for the Fan0 Output and one for the Fan1 output filtered through the Buck Converters to convert to 12V. This larger electronics case accommodates the two LM2596 converters and a Radio Shack 276-150 Circuit Board which I built the distribution block on. The top panel is divided into an upper and lower lid, the lower lid slides into a mount on the left side and lowers down with the right wall under the upper lid to keep it in place. The upper lid slides into a mount on the right side then has holes that line up with the case which can be attached with two M4 screws. I used the lock nuts to ensure a hold even if the plastic strips over time. I have included two Lower lid files, one has a cutout to view the voltage on the two Buck Converters, the other one is solid and does not contain the cutouts in case you want to use the case without those converters. The pegs that they mount to can be broken off with pliers if you choose not to use them. I have been using this case with no issues for a couple weeks. In regards to the amperage draw from the Fan1 and Fan0 - I have been using these accessories on the printer for about five months (printing almost daily) with no negative side effects. Below is a list of the accessories that I have attached to the printer: Fan1 Extruder Fan - Noctua 40mm Case Fan - Noctua 40mm Lighting - Peel and stick Roll of 12v white LEDs cut in three sections, two sections with twelve LEDs each mounted under the X axis frame, and one section with three LEDs mounted under the extruder fan in a custom fan grill with LED holder. Fan0 Bed Fan - 60mm Noctua in custom mount (see other designs) Three Scythe Super Kaze 40mm fans for cooling the stepper motors (X, Y, and Extruder) The distribution block has one open port still on the Fan0 Side, and I have tested it with an additional fan in the event I choose to upgrade to dual extruder. My Z motor never even gets warm.
