A smal turn for a wheel - a giant leap for accessibility!

Inspired by stair climbing hand trucks and the old Lockheed “Tri-Star” Design it lets you easily scale stairs, bumps or any other rough terrain.

If one of the smaler wheels hits an obstacle, the whole assembly will rotate and the stroller can move on.

This model is designed to let you replace the main wheels of your stroller with a central "star" and three scooter wheels per old wheel.

This version is designed to replace a 240mm main wheel and use 120mm scooter wheels.

The exact hardware needed depends on your specific type of stroller. In any case you will need per main wheel:

3x Scooter wheel (incl. bearings)

2x Ball Bearing 608ZZ or equivalent

3x M8 Bolt ca. 55mm

6x Self-locking nut

3x big washers (e.g. Iso 7040)

9x normal washers

To enable you to adjust the model to your specific needs I included the STEP file.

I am looking forward to your makes and remixes!
