This is the 3rd version of the T-Mobile Trashcan cooler, that I've designed. It's based around the 120mm Noctua Desktop fan. It's 137mm (L), 137mm (W), and 76m (T).

I also used M3 brass inserts to put it together, however, I'd imagine if you had a long enough bolt, that would also work.

It's slit up into 3 parts to make it easier to print.
