working turbocharger

To test my latest compressor housing I created this turbocharger to be powered by a vacuum cleaner . It may also work with compressed air or other gasses ( to be tested )

requires : printed parts
intake , exhaust housings
25mm housing adapter
2 pc housing back plates
2pc 25mm backer with bearing
1 each turbine , impeller
other parts :
6mm shafting/ tube ( I used stainless steel straw )
2pc MR106-77 bearings ( higher quality the better ) ( 4 locations for bearings only 2 required )
10pc m4 x 8 screws
laser cut shims ( may be required depending on print settings and your machine )
