After upgrading from CB1 to CM4 I decided to make a file server out of my old CB1. I found a case model but due to where I want to put it I need the case to be as covered as possible. As a file server CB1 does not need additional cooling but if desired you can also put a passive radiator. As hardware you can use the screws that came with the CB1 module and the Pi4 adapter.
I hope the model helps you!
Happy printing!
The author remixed this model.
I modified the model so that the cover can be opened without tools(just slide the sleeve off) and we gave up on functions and cutouts other than the USB-C and HDMI ports (we gave up on GPIO pins, camera slots, Wifi antenna access, 5V power etc.).
