E3D & Duet3d #MRRF2019 ToolChanger Coozie

Here is my publicly shared submission for the E3D ToolChanger STL competition (http://e3d.online/TCComp). It's a 4 color, multi-material (TPU + PLA/ABS/PETG) coozie. I recommend printing "black tpu" in tpu, but the other parts can be printed in any material you want!
