pi4 Igloo snap tower

I wanted something simple, that wouldn't require going to the hardware store. It should be completely printable and not require any extra hardware, or anything I couldn't print, didn't have any extruded text on it or other eye sores, and was fairly easy to print without any piece taking too long.

Compatible with the Ice Tower cooler, but you will have to have a custom mount for it. I directly mounted mine to the pi4 with screws, and did not use the standoffs/plastic tray that came with it. This is better imo, since you can tighten the cooler against the cpu very tight and use real thermal paste. The screws closest to the fan in front will need to be short to clear the fan, or use a 10-15mm deep fan instead of 25mm.

printing with pla+ or pla2 is better, the harder plastic works better. Hatchbox will suffice, but I would prefer something harder. Filacube pla2 works well, and made in USA. ~210c/55c, 0.2mm.

I recommend printing the bottom, then the front. make sure the two pieces go together well, or you might want to adjust your print settings a bit. They will be tight at first, but put them together and pull them apart a few times to wear them in. They will loosen up a bit. Put the case together and pull it apart a few times before putting the Pi in it, just so you make sure you've worn it in, and can take it apart without hurting the Pi. If needed, I can provide pieces with a larger gap between fittings.

The fan in front is a 60mm x 60mm x 25mm fan. I had a few leftover from a while back, but the Noctua 5v 60mm should work well.

I sand it down lightly with 60, then again with 400 grit using a wet sand. makes for a nice, smooth matte finish.
