This is a very simple Raspberry Pi 5 case designed to be 3D printed without any support material.
It is compatible with the official active cooler, and the power button can be pressed without removing the case. There is no need to use a thin stick or similar tool to reach the button.
The gaps around the connectors are kept as small as possible.

Due to the number of fine details, a layer height of 0.16 mm or less is recommended.

Compared to v1, the main unit is easier to install, and the addition of small protrusions helps prevent the lid from coming off easily.

This case is available in two versions:

Standard Version:
Designed with appearance in mind. Ventilation holes are located only on the sides, and the GPIO pins are covered.

Enhanced Cooling Version:
Designed for better cooling performance. Additional ventilation holes are provided on the top and bottom, along with an opening for GPIO access.

Both versions are also available in a Screw-Optional variant, which is primarily secured by a snap-fit design but also allows optional fastening using M2.5 screws.

As a reference measurement, a Raspberry Pi 5 with the official Active Cooler was subjected to a 10-minute full-core stress test.
The CPU temperature reached 65.3°C with the standard version and 58.7°C with the enhanced cooling version.
