This is a replacement timer knob for my Daewoo 4L air fryer that I made after the original one broke. This is a quick print, taking only around 20 minutes on my AnkerMake M5C. It is quite a tight fit, so feel free to scale it up by 5% if your printer doesn't have good tolerances.

Print Instructions:

Make sure you print this in a heat resistant material, such as PETG. I originally printed this in PLA but it warped due to the heat and didn't work.
I recommend 30% Gyroid infill because this part needs to be strong.
No supports or brim required.

I designed this using TinkerCAD because I couldn't find any replacement knobs for the same type of air fryer that I have. I have also posted this on Printables, https://www.printables.com/model/886381-daewoo-4l-air-fryer-knob-replacement and Make It Real, https://makeitreal.ankermake.com/models/dd6e183216d811efafd1bea26cd53ed7/.

I hope you find this model useful and enjoy the print. Please post a make and leave a comment to let me know how it worked for you. As always, Happy Printing!!
