Front wheel conversion kit for Mutsy Nio

After Mutsy went bankrupt I discovered that there weren't spare front wheels available for my Nio stroller. I ordered spare wheels for the Mutsy Icon and adjusted the locking mechanism of the Nio to fit both the original wheels and the Mutsy Icon wheels.

Differences between the parts: 

• v1 only fits the Mutsy Icon front wheels;
• v2 both fits the Mutsy Icon and Nio front wheels.

Printing instructions:

• Don't add a brim, I already added one which is easy to pull off and prevents the printer from knocking it over;
• Use 0.2mm layer height;
• 30-40mm/s printing speed;
• PLA is fine, Nylon would make the part even stronger and more durable.

Mounting instructions:

1. Remove the original front wheels from the stroller base;
2. Use snap ring pliers to remove the snap rings from the axis;
3. Remove the ring and the original plastic tube from the axis;
4. Slide the 3D printed part over the axis;
5. Apply the ring and then the snap ring to lock everything back in place;
6. Now mount the new wheels.
