Do you need to verify the real consumption of electronic components (such as LEDs, motors, cards, etc.) that fall within the range of 0-100 Volt DC?
This box is for you, simple to make with a 3D printer and the material used is PLA.

I attach links for the possible purchase of the material necessary for completion, feel free to purchase on other platforms as well:
