Ender 3 back-mounted vertical electronics enclosure with 80mm fan (No Supports) Under 100g of Material

After much dissatisfaction with the ender 3 electronics enclosures floating about the internet, I decided it was time to design my own. This is an electronics box for the ender 3 that is mounted vertically on the machine's rear. This allows for much easier access to the electronics, more airflow for the fan, and most importantly: way more slack for the tool head cables. This let the cables go from being strained and impeding into the build volume at max X and Y to having more than enough slack to reach full X and Y routed comfortably outside the build volume. This design should fit most ender 3 boards. I've tested with an original Creality Board and an e3 RRF Pro v3 board, both of which fit. It should also fit on any other machine with a 4040 v-slot bottom frame. This model is also optimised to use much less material than other boxes. The full assembly (box and lid) Is less than 100g of PLA when printed at 100% Infil. Installation tips: In terms of screws, you'll need 4 12mm m3 bolts for the lid, 5 m3 5mm bolts for the board, and 4 m4 35mm bolts for the fan. You'll want the hot end cables to come out of the top hole. You should route the bed cables and motor cables out the bottom side. I'd recommend routing your y and z cables under the bed cable to prevent them from rubbing on the bed levelling knob. You have to remove the fan cable from the fan's strain relief and route it through the fan hole. Optionally, you can install some mesh in-between the fan and the lid to prevent the fan from hitting cables if your box is very densely packed like mine is.
