<b>What it Holds:</b> <ul><li>1x Solid State Relay: MGR D4825 (for the AC Heated Bed)</li> <li>2x 2596 Buck Converters (for 5.2V pi and 12v fans)</li> <li>1x Raspberry Pi 3B+</li> <li>1x Creality Motherboard 1.1.5</li></ul> This was inspired by the Ender Extender Electronics Box credited with Remix. I have an AC Heated Bed on my Ender Extender, so I needed to fit in the Solid State Relay I'm using to turn it on/off. <b>Changes from Original:</b> <ul><li>Increased the height of the box by 6mm to accommodate the SS Relay with Plastic cover and the height of the BLTouch Adapter for the 1.1.5 Motherboard</liu> <li>Added a cutout so I can remove the Pi memory card without having to remove the Pi</li> <li>Added standouts for the SS Relay</li> <li>Removed the cutout letters on the lid.</li> <li>Moved the fan cutout on the floor to the lid. I figured it would be better to pull hot air. I don't know if this makes a difference, but it made me feel better. The fan that I used is a 40mm Noctua fan.</li> <li>Increased Lid thickness to make me feel better about putting the fan up there.</li> <li>Removed the angle for the screw heads in the lid. I had button head screws... too many to buy more</li> </ul> <b>Potential Future Improvements:</b> <ul><li>Fan cover on top of the lid to stop crap from falling into the fan.</li> <li>Wire guides of some kind on the inner side of the outer box walls to make the wiring neater</li> <li>Change the side cutouts to be rounded, so they do not need support. Getting the support out was a pain.</li> <li>making a couple of the box cutouts on the front or back able to hold a USB port extension so I wouldn't have to open the lid to unplug/plug my camera</li> <li>replicating the rest of the ports and wires to a pluggable interface, so it's easier to install and remove the box without having to undo a ton of wires inside</li> </ul>
