CM4 Spacer for use on the Turing Pi v2 CM carriers

When putting heatsinks onto my CM4 compute modules, there's a 1.5mm gap between the CM4 and the carrier board. This makes it hard to tighten down screws in a way that made me feel comfortable they wouldn't fall off. 

This is a stupidly simple model that I put together in openscad to make that space up and allow me to put screws in.

That SCAD file is included, because it is stupidly simple. However, now you don't have to type in those three lines :D

I printed it in ABS 0.1 layer-height to get the 1.5mm proper (0.2 layer-height will stop at 1.4mm) , and turned off single wall for top layer (which was on by default for me).
