5x7cm Circuit Board Box – Development & Mounting Enclosure

Description

This is a 3D printable enclosure designed for standard 5cm x 7cm (50mm x 70mm) prototyping circuit boards. The box features mounting holes that align with the default holes on most perfboards, ensuring secure attachment and protection against short circuits. The enclosure is ideal for development and prototyping, providing a safe and stable base for your circuit board on your desk.
