Description:

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!To build this you need these metric [mm] bearings:(amount x outer diameter / inner diameter / height – link)1 x 47/25/12 –
