Quadro Connectors
thingiverse
I constructed one of the connectors out of embarrassment and then all the others as well. I only printed the T-connector. But it's not really worth it. You can buy the connectors very cheaply in the online shop. https://quadroshop.com/ Printed with PETG, the elements are much stiffer than the originals. With 4 wall loops the ends are 100% filled. I have not managed to destroy them by hand. Still, I only see this as a stopgap when you need a quick replacement installed in a low stress location. https://youtu.be/YKvG014VYCI
