MP Maker Select Mini Berd Air

A Berd Air part cooling system for the Monoprice Maker Select Mini and E3D V6 hot-end. Makes for a lightweight but highly effective part cooling system.

If you can't print the `Berd Air Pipe.stl` then just substitute some 4mm OD brass or aluminum pipe. This is available at your local hobby/RC store. I'd suggest you bend it before drilling holes. If it's too difficult to bend a single pipe in to the correct shape you can also get away with using two pipes and just putting one 90 degree bend in each so that they come alongside the nozzle, then drill appropriate holes so that they are aiming just below the tip of the nozzle.

What pump to use? For PETG, a simple 100-gallon aquarium pump will do. For PLA and other materials, I'd recommend a 12V DC mini air pump from [AliExpress](https://www.aliexpress.com/item/-/33006096807.html?spm=a2g0s.8937460.0.0.48532e0ehQ8wXI)
