My version of Raspberry Pi case.
Tested with Raspberry Pi 3B+, but it should be OK with 3/2B as well.
First place side with HDMI, jack and micro usb connectors into the case holes and than "slide" other side down.
I have not use screws for the lid this time, you can only push the lid down into the case.
If will not fit for you(as each printer is different, different settings, etc) you can modify it as you want(Fusion360 file included).
There is some usefull holes for GPIOs, flex display/camera cables,ventilation, etc.
You can remove/insert SD card easily as well.
I hope that it will be usefull for someone:)
