If you're looking for a printable Arduino object counter enclosure, this design is tailored for makers building an Arduino UNO-based object counting machine. The enclosure features a compact, modern look with smooth, filleted corners and a professional finish. It's designed to house all necessary electronics, including an IR sensor, LCD display, battery, and more, making it ideal for anyone wanting a clean, functional enclosure for their DIY counting project.
This printable Arduino object counter enclosure is thoughtfully engineered for practical use and easy assembly. The design includes a removable top cover secured with four M3 screws, a 30 mm diameter drop hole with an internal 45° sloped chute for smooth object flow, and a dedicated IR sensor mount with aligned slots for accurate detection. The front panel features a cutout for a 16×2 I2C LCD and a grille for buzzer sound, while internal bosses and cable routing channels ensure tidy electronics installation. All parts are separated into print-ready STL files, including the main enclosure, top cover, IR sensor bracket, and LCD bezel, with no supports required for most components.
For best results, print this enclosure using FDM 3D printing with a 0.2 mm or finer layer height to achieve smooth surfaces and strong corners. The design avoids the need for support material wherever possible, making it easy to print. Use at least 3 perimeters and moderate infill for sturdy walls and mounting points. Black matte filament is recommended for a professional appearance, but any standard PLA or PETG will work well.
