About this 3D model

This turbine is based on what is used in jet engines. This model consists of the turbine nozzle (directs airflow onto the turbine disk) then there is the turbine disk which turns . There is a bearing required here are the dimensions for the bearing 5/16 x 1/2 x 5/32 I got this bearing off of eBay for about $5 it's a little pricey but I found it well worth it for this project!
