As a bit of a jab at me my parents dug out the old Playskool pipeworks set my brother and I used to play with as kids 20+ years ago now, they proceeded to tell me I needed to fix the broken pieces that me and my brother broke so that my nephew can play with it, these bits are the green 4 way joiners.
So as I imagine you can guess I am wondering if anyone might be willing to part with one of these sets or what parts you have left, I am happy to consider making offers depending on what parts or sets I can get my hands on.
I am currently trying to 3d print some of these parts but because of how they will be used I am not sure the 3d printed parts will be capable of handling the force\stress that would be put on them and probably crack or break at the layer joins.
This is what it looks like (I need the green bits)
