Thule Pram Brake

thingiverse

I decided to copy the original Thule pram brake hub because mine fell out whilst running. I orientated the print so that the locking pin holes faced up. The problem with that is that the layers are perpendicular to the angle of torque. So to strengthen the tabs that engage in the hub, I lengthened them towards the center axis of the hub. This worked pretty well and to date it is still working. I printed it in PLA and it has worked a charm.
