experimental electric jet engine compressor

This is a multi-part centrifugal compressor designed around a GARTT HF-500 R/C Helicopter motor that I modified for surviving being overvolted. The real impeller I'm using is machined aluminum and from a turbocharger but I made a model of it anyway if anyone wants to attempt printing this highly experimental prototype. I plan to run the 1600kv motor on a 12s battery and get about 71,000 rpm of the impeller. It requires an additional support bearing (5x13x4mm) and is going to be attached to a modified water bottle combustion chamber. This has not been tested yet, so print and experiment at your own risk.
