Lid for LM2596 with Heatsink

I printed a couple of the LM2596 cases by [MichaelFinch](https://www.thingiverse.com/MichaelFinch) and they fit my buck converters like a glove, however mine came with small heatsinks. I threw this remix together in Tinkercad to allow for the heatsink to poke through the lid. You'll need the base from https://www.thingiverse.com/thing:3175937.
