Printable Project Enclosure STL for Electronics and Velcro Mounting

If you're looking for a printable project enclosure, this design offers a practical solution for housing your custom electronics. The enclosure is a two-layer rectangular box, specifically engineered to fit components like an OLED display, speaker, ESP32 C3 Supermini, charger board, battery, MPU6050, and MAX98357A DAC. With dedicated recesses and cutouts for each part, this print-ready STL is ideal for makers who need a reliable, customizable case for their DIY electronics projects, especially when mounting to a stick or shaft using Velcro straps.

What Makes This Model Stand Out

This printable project enclosure features a thoughtful two-layer design. The top layer includes recessed pockets for the OLED and speaker, allowing them to be pressed in from the outside and secured with superglue. There are precise cutouts for USB ports on both the ESP32 and charger board, each with a glue ledge for easy mounting. The bottom layer is an open tray with matching screw bosses and pilot holes for M3 screws, making assembly straightforward. Three robust, minimal-protrusion strap tabs are integrated on the bottom, designed to anchor Velcro straps securely and orthogonally to a stick. The enclosure also provides generous fit tolerances and wire routing holes, ensuring easy assembly and reliable connections between components.

Recommended Print Settings

For best results, print this project enclosure with a standard layer height for a balance of strength and detail. No supports should be necessary, as the design is optimized for easy printing. Use moderate infill to provide durability, especially around the strap tabs and screw bosses. PLA or PETG are both suitable filament choices for functional enclosures like this. Ensure your printer is well-calibrated for dimensional accuracy to maintain the intended fit for all electronic components.

Use Cases

• Custom electronics housing for DIY projects
• Mounting sensor and control boards to a stick or shaft using Velcro straps
• Prototyping portable devices with accessible USB ports
• Securing components with superglue for field use
• Organizing and protecting small electronics in a compact, print-ready STL enclosure

Frequently Asked Questions

• Does this printable project enclosure require supports? No, the design is optimized for support-free printing.
• What screws should I use to assemble the layers? The enclosure is designed for standard M3 self-tapping screws, which are widely available.
• Is there enough room for wiring and component fit? Yes, the enclosure includes extra tolerance and routing holes to accommodate wires and ensure a comfortable fit for all listed components.
• Can I adjust the size for different components? The design uses variable parameters, so you can modify the STL or SCAD file if your components differ in size.
• What filament works best for this enclosure? PLA or PETG are recommended for strength and ease of printing.
