My Britax Römer Smile 3 front wheel locking and turning mechanism broke so I took it apart and modelled the parts to be 3d printed.
You can use all the original screws and spring when reassembling. After replacing the parts the wheel works as originally intended.
I printed the parts with Polymaker PA612-CF
0,1 layer hight and 100% infill.
These parts will also need supports for printing: "Vankri nupp", “Vankri ülemine pool”, “Vankri alumine pool”
Sadly I don't have pictures anymore as the stoller has since been sold.
The author marked this model as their own original creation.
