he alos mentions in the comments about the other parts used
For the other parts, I used:
- 12 rollerblade wheels with ABEC1 bearings
- 12 "L" metal plates
- A thick and heavy wooden plate (50x80x2,3cm)
- Some skateboard grip
- Bolts, nuts, rings
- AND (I forgot to mention it) a "GRUNDTAL" toilet paper dispenser as a handle!
