This is my case to add a Raspberry Pi 4B to an iFactory One belt printer.
Originally there is an Pi 3A inside with only one USB port and no network port.
As cooling solution i went with Raspberry Pi Horizontal Ice Tower Cooler from GeekPi with a fancy RGB Fan ;)
The used display is an OSOYOO 3.5" TFT.
Hopefully someone can use this.
