If you're looking for a printable electronics enclosure, this is a functional design built specifically for makers and engineers who need to house Arduino boards, motor drivers, power supplies, and DIN-rail components in a single, organized box. This print-ready STL is a 130 x 240 x 150 mm enclosure with a screw-on lid, four cable gland ports, and integrated mounting points for common electronics. It's designed to be printed in PETG on a standard FDM printer without supports, making it practical for prototyping, robotics projects, and industrial control applications.
This printable enclosure is engineered with specific internal geometry to accommodate real components. The design includes dedicated mounting zones for an Arduino Uno with M3 threaded standoffs, a 40 x 40 mm motor driver footprint, and a full DIN-rail system (TS35 top-hat rail per IEC 60715) that runs along the floor with integrated mounting bosses. The four M16 cable gland holes are split across the two short end walls for balanced cable routing, with 30 mm center-to-center spacing to allow room for gland nuts.
The 3 mm wall thickness is intentionally robust, designed to handle screw bosses and DIN-rail loads without flexing. A silicone gasket groove in the lid provides basic dust and splash protection. An open wiring channel between the Arduino/motor-driver zone and the DIN-rail zone keeps cable routing organized and prevents component collisions. The internal usable height of approximately 144 mm leaves clearance above a 110 mm tall power supply for wiring and potential ventilation.
This enclosure is best printed in PETG for durability and chemical resistance. Use a layer height of 0.2 mm for structural integrity, particularly around the screw bosses and cable gland holes. Print with 100% infill or high infill (90%+) to ensure the walls and mounting points are rigid enough to support screwed components and DIN-rail loads. No supports are needed if your printer can handle the internal geometry; the design is optimized for support-free printing. Print slowly (40-50 mm/s) to maintain dimensional accuracy around the threaded inserts and cable gland holes. Allow the part to cool fully before removing it from the bed to minimize warping.
This printable electronics enclosure is a complete solution for makers who need a functional, organized housing for their projects. Both STL and STEP files are included, so you can print it as-is or modify it in CAD to fit your exact component layout.
