Original tools:

3.5 Nm to 4.5 Nm source: https://www.youtube.com/watch?v=TfHsCjCEYI4&t=573s

My attempted settings:

  • Material: PETG Basic

  • Nozzle: 0.4mm

  • Wall loops: 6

  • Infill: 35%, rectilinear

You can try using a C clamp around the opening and see if it works. Nevertheless, I posted the model for others to try their hand at remixing a better version.

Otherwise, I'd recommend this setup instead:
