Duplo Technic pin
Description
I've scaled up a lego technic pin to fit duplo technic parts found on aliexpress. I couldn't find any existing pins for duplo sized parts so used the dimensions from ortwins duplo models to create this file. I have tried printing both vertical and horizontal(with supports) and my advice is to print horizontal. As you can see in the 3rd picture I have put the pins under some serious stress tests and only the vertical printed pins have broken so far. It seems the vertical layer lines run along some of the high stress points.
