Spools for Infento rockboard scooter

3D models of the spools for needed for creation of the Infento rockboard/spacescooter
 

for complete CAD model please see my OnShape model

The other parts needed are

bearings: 2x 6905ZZ (these are also used in standard Infento bearing blocks)

10x M6x12 socket head bolts, 10x M6 locknuts

2x Infento freewheels

Assembly: be aware that each freewheel is mounted in different orientation

Apart from that the ride also uses two 3D printed pulleys:

I print everything with 0.28mm layer height in PETG. PLA should be also fine.
