Rhoyxon Hob's gas knob extension

thingiverse

I'm upgrading my old Rhoyxon hob by installing extension caps on its gas knobs. My hob is due for replacement, but these modifications make it safer to use. The faded gas position indicator nearly caused a disaster when one ring was left open overnight. These custom knob extensions provide instant visibility if any gas ring is in an open position and how much. I designed them with curved heads that don't need clips or clamps. They're secured using blutack or double-sided tape, which holds up well under heat. The PLA-printed caps can withstand the intense heat from nearby gas rings at full capacity.
