Stroller wheel puncture free

Designed a set of front tyres for our brio smile stroller.This model should be possible to scale to fit any rim.Fits rim diameter approx 144mm (r=72mm)32,3mm inside rimPlease have a look at dimensions below.I printed this with fuzzy skin and TPU 95AIts a bit stiff but works great for us during the last 2 years.The installation is a pain, i put the tyre in the owen to make it softer approx 100C for 10 minutes and then used zipties to get tyre over the rim.
