Ender 3 Pro SKR Mini E3 Case

03-16-2020: I've been told by okalvo86 that the stock z axis cables are a little a couple cm short. Be aware of this before you build it and have a plan for extending or replacing your cables just in case yours are too short. I wouldn't know, my cables were mangled when I got my printer so I made my own.

STL THUMBNAILS ARE NO LONGER SHOWING UP. NOT SURE WHAT'S GOING ON.

IF ANYBODY HAS ANY SUGGESTIONS I'D APPRECIATE IT. THANKS!!!

EDIT 03-09-2020: I added a box for the Raspberry Pi 4. I have NOT printed it yet so I have not verified the fit of the Pi 4 in it. I also added boxes for the Pi 3 and Pi 4 that have the Pi shifted to the right side and a small cutout placed directly across from the USB power connector. This will allow you to power the Pi from a wall wart instead of a buck converter...for those that don't have or cannot figure out a buck converter.

EDIT 01-18-2020: I added the files for the newest version of the SKR Box. I removed the need for any mounting hardware. It should snap into place and the 40x40 cover will help to secure it in place.

I uploaded a version of the Raspberry Pi Box for the other side. This is something I am still working on so please let me know if you encounter issues or you find areas that don't fit properly. The lid for the Pi Box should just be a mirror of the SKR Box lid so I did not upload an STL. The Pi box has mounting holes for two buck converters, one for using 12V Noctua fans and the other to power the Pi.

In my setup I am using XT60 Y connectors I bought on Amazon: https://www.amazon.com/gp/product/B0179IODB2/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

The buck converters were also purchased on Amazon: https://www.amazon.com/gp/product/B01GJ0SC2C/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

I'm working on a mosfet box that will go in the back. The box will have an attached cable-chain option for the heatbed. It will also have space for a relay module for powering the printer on and off.

STEP files are included for people that wish to remix these parts.

EDIT: I will be adding a Raspberry Pi box that will have mounting locations for 2 buck converters and hopefully space for a relay module. The relay may end up in the back near the mosfet case I'm making though. I added a picture of the Pi Box so far.

This is for the Ender 3 Pro with the 40x40 extrusion on the Y axis. I will be putting up the STEP files so people can remix it for the original Ender 3 if they'd like.

I wanted a case for my Ender 3 Pro that would make the main board easily accessible. I also wanted the USB and SD card slot in the front, more forward than the stock case. This puts the SD card slot and USB forward of stock by ~50mm.

This case has a sliding lid for easy access and a 40mm fan that draws air from underneath and ports it through the vents in the front and through the lid over the motor driver heatsinks.
