About this 3D model
Connector for ptfe tube to Ikea Skadis/Uppspell PC4-M10 fitting fits into the model, it just requires more force to be applied. Printed from PetG. This model is inspired by this I adjusted the dimensions to fit the model onto the board without damage, while still securely holding it in place. I also slightly reduced the size of the part with the hole and thread. I also created a version with a smaller diameter hole that precisely fits a 4mm PTFE tube.
