Raspberry Pi 4 Mini Desktop Case - Ice Tower Cooler + Secondary PCB Cooling Fan

I HAVE MADE A V2 OF THIS CASE WHICH IS MUCH NICER THAN THIS ORIGINAL VERSION! IT HAS SEVERAL QOL IMPROVEMENTS, A DUCT THAT FIXES A FITMENT ISSUE MANY PEOPLE REPORT HAVING, AND IT IS COMPATIBLE WITH GEEKWORM M.2 BOARDS WHILE STILL RETAINING THE SAME OVERALL SIZE. https://www.thingiverse.com/thing:4768816 8/21/2020 I made a version of this case that fits the GeeekWorm X872 m.2 NVME expansion board. https://www.thingiverse.com/thing:4576177 If you want to try out the secondary fans without printing a whole case: https://www.thingiverse.com/thing:4270044 5/4/2020 I added a revised structure part. Not a big change, I just increased the side of the hole the m2.5 screws go down into to accommodate larger screw heads. I had a builder tell me that the screws in his Ice Tower were too short to go through the structure part and the Ice Tower brackets and screw into the standoffs. So I got some longer (m2.5x6mm) screws from Fastenal and the heads were too big too go down the holes. So I made the holes bigger. I also added a hollow top panel (plank) that hopefully will print faster and better than the original solid version. And finally, I added a bottom plank which is also hollow, but also has screw holes under the recessed where the rubber feet pads are intended to go. These screw holes are the same dimension as the mounting screws on the Pi (49mm x 58mm). These are intended to accomodate rails for a 2.5" harddrive or SSD up to 9mm thick. The rails are at this link: https://www.thingiverse.com/thing:4333866 04/07/2020: I added three items that have 4040 in the name. These are a USB side with a funnel for a 40mm fan, a duct for a 40mm fan, and an HDMI side without the funnel for use with a 4020 (20mm thick) secondary fan. Some fans are a little thick to fit easily with the 40mm duct. Noctua 40mm fits nice, but they have rubber around the mounting surfaces. Cheap fans that are all plastic are tighter fit. Assembly of t
