If you're looking for a printable electronics enclosure, this rectangular project box is designed specifically for makers and hobbyists who need a functional housing for circuit boards, microcontrollers, and small electronics. The box measures approximately 100 x 70 x 40 mm and features a separate snap-fit lid that sits securely into an inner ledge. With built-in cable pass-throughs and mounting holes, this printable box is ready to protect and organize your electronics projects right out of the printer.
This electronics enclosure is engineered for practical use rather than decoration. The design includes several features that make it genuinely useful for real projects:
The focus is on clean mating surfaces and printable walls, which means the lid will fit smoothly and the overall structure will be reliable across different printers and filament types.
This printable box benefits from settings that prioritize dimensional accuracy and surface quality over speed. Since the snap-fit lid relies on precise tolerances, consider these guidelines:
Test-fit the lid before removing support material or finishing. If the fit is too tight, a light sanding of the inner ledge can improve the sliding action.
Do I need supports to print this box? No. The design is optimized to print flat on the bed with the base down, so no supports are required. This keeps print time and material waste to a minimum.
Will the lid fit securely without glue or fasteners? Yes. The snap-fit design uses a 2 mm deep inner ledge with a light sliding fit. The lid should sit snugly without additional fastening, though you can add a small dab of super glue if you need a permanent seal.
Can I modify the cable pass-throughs or mounting holes? Absolutely. The STL is a starting point—you can remix it to add more holes, change their size, or reposition them to match your specific project needs.
What filament works best for this enclosure? PLA and PETG both work well for general electronics housing. If you need chemical or temperature resistance, consider ASA or ABS. The 2.5 mm walls provide good strength across most common materials.
How long does this box take to print? Print time depends on your printer and settings, but expect 4-8 hours at moderate speeds. The hollow interior keeps material use and time reasonable.
This printable electronics enclosure is designed to work reliably on most FDM printers. The focus on clean mating surfaces and printable geometry means you'll get a functional box that actually fits together well. Download the print-ready STL and start your next electronics project.
