Took me a good evening but I finally sat down and drew a shell for the SnesDrone board in Tinkercad. It features holes for the PCB mount potentiometers of the new PCB design and it SHOULD fit into NTSC and PAL consoles. Haven't tested this yet due to a lack of an NTSC console though. :D
In case you want to print this, here's the link to the tinkercad project: SnesDrone Tinkercad Shell
As you can see in the new profile picture to this page, it prints pretty well!
