<p>Remix of my own design. I had a lot of positive response so i desided to redesign it and use metal bearings to avoid friction problems i had with the 100% 3D printed version. Runs much smoother now!</p>

<p>I also tried to design it with 3d printed bearings - But did not work that well. I could get these bearing in an industrial store in my town for around 35 €. The bearing are standard sizes - so you should get them easy.</p>
