ARDUINO HOUSING
ARDUINO HOUSING
Embedded Files
Design and fabricate a custom housing for an Arduino Uno, using laser-cut acrylic panels and a 3D-printed spacer. The housing must meet specific size, assembly, and tolerance requirements while incorporating Pettis joinery.
OBJECTIVES
OBJECTIVES
Material:
Made from acrylic sheets, typically 3mm (1/8 inch) thick for durability and transparency. Acrylic is chosen for its ease of laser cutting and clean finish.
Pettis Joints:
Interlocking joints that create a secure fit without adhesives or fasteners. Designed for precision assembly and a seamless appearance. Requires precise cut tolerances to account for the kerf (material removed by the laser).
Design Considerations:
Ensure cutouts for USB ports, power supply, and pins are precisely aligned with the Arduino. Plan for easy assembly and disassembly for maintenance or upgrades.

Important Considerations
Important Considerations
Tolerance: Account for material kerf (laser-cut acrylic) and shrinkage/expansion (3D printing).
Spacer & Locator Design: Ensure precise positioning and secure mounting for the Arduino PCB.
Edge Overhang: Prevent screws or hardware from extending beyond the panel edges.
Panel Connections: Ensure Pettis joints fit tightly and allow easy assembly/disassembly.

Attach the Arduino to the spacer snap tabs.
Secure the 3D-printed spacer to the housing’s side panels.
Assemble the bottom and top panels using Pettis joints and screws with square nuts.
Verify the alignment of all components and adjust if necessary.
