This model is a replica of the propeller from the FP propeller company. I made this static model, because I wanted to have propeller on my wall. The propeller has 1.8 meters in diameter. Here is the refferce for the real proppeler from the company: https://www.fp-propeller.com/e_propellers_fp2.html
I printed all the important pieces to be sure everything fits and moves freely.
In the zip file with STLs, there is the manual, where are photos, non-printable parts, and a description how to assemble it.
There are just two parts that need supports. I tried to make it support less but it was very problematic so I decided to use them.
