Connectors for wooden toy rails e.g. Brio

As the connectors are regularly lost, the question arose: can't we do it ourselves?

We briefly measured and digitized them in Fusion and then picked out the right filament. The task here was that it had to be stable, it had to be used by children and it had to be particularly suitable for toys... The choice was already made, Extrudr NX2 is FDA-compliant and fulfills the Safety of Toys regulations
