Ice Cube Case for Low Profile Ice Tower Cooler for Raspberry Pi 4

Pi 3 Version Here https://www.thingiverse.com/thing:4223596 --- This is a case for the Low Profile version of the Ice Tower Cooler for the Raspberry Pi 4. It requires 8 m3 x 6mm or M3 x 8mm screws to assemble. The board itself is not attached with any fasteners, it is help captive by protrusions on the inside of the case. It is designed to be used with only one set of the standoffs that come with the cooler (the ones between the Pi's PCB and the brackets for the cooler). The screws that are intended to hold the plastic bottom cover to protect the bottom of the Pi (included with the Ice Tower kit) are used on the bottom of the Pi PCB to retain the spacer standoffs. There's a basic version that just a hollow box, and the regular version which has some rudimentary ductwork around the exhaust ports - which seem to have very little effect on cooling. The pieces are intended to be printed flat on their rectangular faces with the triangular faces pointing upward. In this orientation they require little support. The screw holes benefit from support, and the dimple for the SD card needs support. On my Ender 3, with Cura default settings, the short sides print in about 90 minutes (each) and the long sides print in about 120 minutes (each). There is a video showing details of this cooler, this case, and reviewing thernal testing of the Low Profile Ice Tower compared to the original taller version. https://youtu.be/TFpoVwrw3Pc
