I have quite a wide experience with 3D printing, including cases for electronics (phone cases, Raspberry Pi and custom PCBs enclosures etc) and ready to provide my services to you.
Contact me before placing an order with specs of your electronics (gabarite / mounting deimensions of PCB, model of your electronics, preferably its datasheet etc.), 3D printer (type, working area, minimum wall thickness and feature size etc.).
Please note, that depending on your 3D printer and filament specs (thermal shrinkage coefficient, precision of printing head etc) the model may require some adjustment and several revision prints.
