Makergear M2 Larger Electronics Box with 2 LM2596 Holders by dellrio

Last crawled date: 3 years ago

I have converted all the fans on my printer to 12v noctua fans for lower noise levels. Since the Printer pushes 24volts I needed 2 LM2596 Buck converters to convert the output to 12v. I also added active cooling fans to the X, Y, and Extruder motors and have added LED lights as well. I built a distribution block with 2 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 2 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 2 M4(I think - extra screws from the M2 Kit) screws. The holes are tight enough you can screw directly into the plastic and it did hold for me, but there is also a slot to insert 2 M4 Lock nuts (also M2 extras). I used the lock nuts to ensure a hold even if the plastic strips over time. I have included 2 Lower lid files, one has a cutout to view the voltage on the 2 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 5 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 3 sections, 2 sections with 12 LEDs each mounted under the X axis frame, and one section with 3 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)
3 Scythe Super Kaze 40mm fans for cooling the stepper motors (X, Y, and Extruder)
The distribution block has 1 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.
