The model is designed for a 0.4mm nozzle.
Other nozzles can of course also be used, but the function can suffer as a result. I used super glue to glue the connections.
If you find a better glue let me know.
If you find an error in the model or have an idea for an improvement, let me know and I will change and upload the new model.
