This is a remix of the original, closed case for a relay module. The main modification consists of a large opening at the bottom.

Main Difference from the Original:

The original case is completely closed at the bottom. This means that the cables get in the way when you want to remove the top part (the lid).

My remix solves this problem with a cutout:

• Accessibility: The opening makes it possible to remove the top of the case without having to disconnect the attached cables first. This significantly simplifies maintenance, troubleshooting, or modifications.
• Design: The design maintains the protective function while improving handling when installed.

Additional Advantage

In addition there is a practical side effect for 3D printing:

• No support needed: Due to the open design, printing the case is easier and no longer requires any support structures, which saves material and reduces post-processing.

This case is ideal for makers looking for a more maintenance-friendly solution for their relay modules.

Thanks to the original designer for sharing the model!
