caixa CNC Sheild Arduino

 This project is based on the model provided by the professor, with improvements made to optimize the design and functionality of the enclosure. The main changes include:

Rotating Lid System: Instead of the lid being screwed with four screws, I opted for a single screw, allowing the lid to rotate easily. This facilitates better access to the interior of the box.

Additional Stability: To ensure better stability, I added a tab on the lid that fits securely onto the top of the box, ensuring the lid stays in place.

Wider Hole for Wire Passage: I replaced the multiple cylindrical holes for wire passage with a single, larger square hole. This change makes it easier and more organized to pass wires through the box.

Improved Ventilation: I modified the design of the holes in the box walls, adopting a different shape, with some holes being wider. These changes aim to improve ventilation, ensuring that internal components stay properly cooled. Instead of the standard cyllinder holes  I replaced the honeycomb shape with octagonal holes. This alteration makes the design visually distinct while maintaining the functionality of allowing air to flow through and cool the internal components.

Top Lid Modifications (Tampa B): For the top lid, I made design changes too. The original version had a series of cylindrical holes, which I replaced with a rectangular shape. This new design occupies the same area as the previous holes, but with a more streamlined and organized look. The lid also features a small groove at one edge to allow for easy attachment and detachment, ensuring a secure fit while still offering quick access when needed.

Additionally, it was used in both versions the enclosure() module in OpenSCAD to define the structure of the box, including the base, walls, ventilation cuts, mounting holes, and spaces for the Arduino and other components. Lateral ventilation was enhanced using the fan() module, which employs the minkowski operation to create a smoothed grid. Four symmetrical cylindrical holes were added to ensure proper airflow, contributing to the cooling of the internal components
