Macintosh IIcx case for a Raspberry Pi 4

This is an ~40% scale model of a Macintosh IIcx case that has been set up as a Raspberry Pi4 case.  The model includes mountings for a Pi 4 and a 40mm case fan.  There is an optional shelf in the front where a green LED may be mounted similar to the Mac IIcx case.  The design is not perfect, but it generally looks a lot like a IIcx.  Painting it platinum and added a custom decal finishes out the look.

This model is written using OpenSCAD and the source code is included. It has not been fully parameterized (e.g. one cannot just pick the size in % and regenerate it), but it is close.  Some aspects of the slots, LEDs and clamps would need additional work to parametrize.  The code includes a simple Raspberry Pi 4 model that includes standoffs and output blocks for the USB and Ethernet ports.  The USB-C power and HDMI cables are routed through an added hole that supports a standard ¾" (M19.05) rubber gasket for clean cable egress.

Screws are used to mount the Pi (4) and the fan (4).  The lid sits on top of the base and has four slots/channels that engage as the lid is slid into place.  The lid can be fastened to the back of the lower case via one additional screw.  All screws are standard M2.5 self-tapping screws.  Lengths will depend on the specific fan used, etc.  

The fan is powered from the GPIO header (+5v, GND) and a green LED is being powered from the GPIO header (+3.3v, GND).  A chunk of diffuser material fills in the hole in the lower right corner of the face and the green LED is hot glued into the back to provide the “powered up” look.
