I had not found appropriate case for Ender 3 electronics and customise one from site for my user cases
Why do I need this case ?
I use printer at home and commonly use PLA and PETG types of filament and I am not going to use termo box for my printer.
The original Ender 3 drivers are too noisy. I have to replace its. Unfortunately, original Creality motherboard does not support driver replacement. I liked the products of BigTreeTech company. The SKR 1.0 is too old, has less memory, less performance and comparable price. SKR 1.2 is situable, but I bought SKR 1.3 and 2208 drivers at a profitable price. Also I was going to install Octoprint service to some platform and it requires some case for electronics.
I connect SKR motherboard and Orange Pi by UART inside case (according BigTreeTech documentation) and use SD card exender on front of the printer.I do not change the original Creality LCD and encoder, for me they work fine. I use them only for bed calibration, preheat hotend and change other printer options. For manage print task I use the Octoprint server through WiFi connection.
I am gouing to use relays to manage power supply and LED light.
Unfortunately, I received the relay modules after assembling the case and still haven't connected them. At the moment I am using switches to control the light and power of the SKR and can't remote manage power and light. The Orange Pi works in standby mode and I can connect it everywere and averytime. The 5V DC power supply is used to supply Orange Pi and LED light.

Unfortunatly, I can't upload FreeCAD source files to this site. I have uploaded its to Google Drive.
The project was developed some times ago and sources can include not all project parts.
I edited left side separately, because my old laptop had some performance problems..
This is all I can found.
