Needed a larger and easier to turn knob for my blowtorch nozzle due to some dexterity issues, but did not want to break the original removing it. This design solves that by modeling the original handle almost exactly, giving a good friction fit. Should print pretty easy in most materials, I like PETG so that's what I recommend for strength.
Important print settings:
- 0.15mm layers (you could probably get away with higher, may need to experiment with cooling and speeds to make the knurls print well)
- Overture PETG at recommended speeds
- 3 perimeters
- 0 infill
- Flat/top face down
I included a picture showing a 'topless' prototype to show how/what it fits. This model is included in downloads in case you want one without knurling for easier printing, but it is otherwise not recommended over the 'V2' model.
