This protective box came alive with short circuit protection in mind. Protects your converter/amplifier from all sorts of elements such as physical damage, water to some point while letting the heatsink to do its job. Has holes for the wires and a snap on lid with an internal rail for fixation. The model on the pictures was the newest prototype but the feet on the inside were to too thick so i lowered them back to my original idea so its perfect now. Printed in a random White PLA.
