Box for DC-DC Converter

This is a bespoke box for a very cheap DC/DC buck converter which I frequently use to efficiently downconvert the voltage from the 12V supply on bord of a sailing yacht to any value needed. The converter comes fully assembled on a PCB without protection and can be ordered here: https://www.banggood.com/Mini-DC-DC-Converter-Step-Down-Module-Adjustable-Power-Supply-p-920327.html

You just have to drill two holes for the power cables on two opposite sides in the lower part of the box and glue (fast hardening epoxy resin) the top of the box to the bottom.

Additionally I recommend to fasten the cables and the PCB inside of the box, which can be done for exmple by hot glue or epoxy resin.
