Plain Pi 4 Case With Tower Fan Option

thingiverse

I purchased a version 4 Raspberry Pi and an S2Pi Tower Fan but couldn't find a suitable case to fit them together. So, I created one using OpenSCAD, a Customizer model that doesn't require the tower fan since its cutout hole is optional. This case comes in two parts: a bottom piece bolted to the motherboard and a top piece with a light friction fit onto the bottom. To secure the bottom case to the motherboard, you'll need four 2.5mm diameter bolts inserted from underneath. If using an S2Pi tower fan, you'll also need to secure the bolts into the brass standoffs that mount the fan to the motherboard. Alternatively, if not using a tower fan, you'll require four 2.5mm nuts as well. The length of the bolts is adjustable so you can use what you have on hand. After mounting the motherboard to the bottom case, place the top case over it carefully, navigating the tall, thin parts between the USB ports and Ethernet port. These components are fragile, so avoid bending them. One drawback of this design is that there's a significant gap beneath the ports, resulting in space underneath the motherboard. However, this case fits easily into the Raspberry Pi and minimizing the space can be achieved by using short bolts with a minimum length of 10mm. I used 22mm bolts, which resulted in a relatively large space.
