USB Load Tester Case

This is a snap-fit case for the relatively cheap 15 Watt USB load tester that is available from many sources online. I was using it with my CT-3 USB test meter and got tired of touching the bare electronic board while using it so I took the time to design this case for it. The case is a snap-fit case and covers up all the electronic parts. I designed it so that the main parts are away from the heatsink so that we can use PLA for it. So far PLA seems to be holding up as the fan kicks on to cool the heatsink down but I only do load tests with 1 amp load and not the max 3 amp load. For my 1 amp tests though, It seems to be doing fine with regular PLA. The load tester I bought on Amazon was the ‘DZS Elec Mini USB 0.15A-3A Electronic Load Tester Module Adjustable Constant Current’ but there are many of these that look exactly the same on ebay, aliexpress, etc. They all appear to look the same dimensions but I of course have do not know for sure.
