- Print turbine upside down to avoid sagging
- Before assembling, remove excess material and surface irregularities
- Use silicone oil (but not silicone grease) to lubricate axis.
- Requires running-in(like new engine).
For the micro chain check out my other projects.
You can use spectroid android app to check revs of your whistle:

How do i count revs?
- Note the frequency(for me >5kHz)
- Divide by 8-becouse turbine have 8 blades and lid have 8 pockets, theres 8 “pings” for one rotate
- You got RPS- for me ->625
- Multiply by 60- for me→37500 RPM
