Nice Model Tolerances are fine.
@TheOnur Thank you! Your print looks great
This printed out fairly well, though I did have to reprint the tc-screwpin and the tc-adapterpin since they broke when I tried to force them in. It was likely a combination of me being too forceful and the filament needing to be dried. In order to fit the ball into the press, I used an allen key of the same size as the screwpin to keep from breaking another pin.
Once together, it works great, and gives my kids more options for their tracks.
I used the recommended print settings, and Atomic Filament's Neon Orange PLA.
@DStrohm Thank you for sharing photos, and for the comment! Great catch calling out the recommended settings. Looking back, I don't think 20% is sufficient for those pins. I'm going to update the recommended infill for the pins to 50% or higher. Thank you again, and I'm glad your kids are making use of them! :)
