Solar panel terminal box

thingiverse

This box, placed at the back of the solar panel, offers a space for connecting external wiring to each panel and adding a diode if needed. To create your own cost-effective solar panels, you can use this terminal box, as commercially available options are expensive. The box includes various hole options that will be revised based on the progress of your solar panel project. It requires 2 x 12mm long M4 machine screws for terminals and 1 x 20mm long M4 machine screw to secure the lid. After printing, use a 4mm drill bit to clear out the holes, place three M4 nuts in the central nut chamber, fit the two outer terminal screws with washers, and attach the lid using the 20mm long M4 machine screw. Future adjustments may include changing machine screw sizes and creating a larger version of this box as your project advances.
