Summary

I was printing number of connectors for IKEA trains and Brio, they were either too tight or too loose. So I created a customizable version. Just use callipers to measure your connector or holes.

I included a preset (connector.json) for IKEA Lillabo train set.

Print Settings

Rafts:

Doesn't Matter

0.2mm

Notes:

Full version with 20% infill is a bit faster to print than the Hollow version and so far I think it's more durable.
