Cooker knob for REX kitchen

I needed a replacement knob for my mom's REX kitchen, so I made that one that is the exact copy of the original one, with only one difference: the original one costs about ~50€ each, while this one printed with settings indicated here costs about ~0.11€ each.

I printed it with PETG filament for more resistance, I don't know how could it be printed with PLA... let me know if you do! ;)
