Inventum GF552HL airfryer timer knob

Original knob started "slipping" when rotated, making it very hard to activate or shut off the airfryer. Decided to print a replacement if I could. Kudos to @Mich21050_518668  for sharing the f3d file so I could base my version off of that - see differences.

Printed in PLA, with 20% gyroid infill, 6 wall lines (trying to make the stem as sturdy as I could, as that is the weakest part - will see how long this holds! If you put the seam on the side where the indicator is, it is almost like an extra indicator stripe on the side ;-) 

Knob slides on a bit difficult (also because in my case the timer unit  is a bit loose in the housing, sliding to the back when pushing the knob on), but adding a tiny bit of “silicon grease” to the inside of the knob stem and the metal rod where it is pushed on helped.

-changed outer and stem dimensions to fit the hole on the Inventum airfryer
-relocated the indicator stripe to the correct site for the inventum and recessed it, so it can print easier in one color
-filled in the knob body higher so it supports the stem further up
