About this model

The original shell as designed by ChrisKewl is perfect for the C64, PET, and Vic-20. However, the Plus/4 has a user port which is ever so slightly more narrow than the other 8-bit Commodore systems. In order to make this work with the Plus/4, I have shaved just 2 millimeters off of either side of the shell, which provides just enough clearance for the shell to fit in the slightly smaller user port. The top half is unmodified, and so I have not included it here. You'll have to get that from ChrisKewl's original design. Note that this means the user port connector is not fully encapsulated by the shell anymore. This might make the part slightly more fragile but it should be fine if you aren't unreasonable in how you plug and unplug it.
