I was sick of the cable salad. Becaus we have a 3D Printer now i did some cases based on other designs which take the cheap 2 Euro MCP2515 Ebay module and a Raspberry Pi B+,2 or 3 conveniently.
Check out the previous german post to see some pictures of the case. It was printed with transparent filament which lets the entire case illuminate at night.
It is now much more organized in the case without risk of short circuits etc.
