I bought a 2023 Forest River Arctic Wolf camper and the first time that i used the outdoor kitchen the plastic knobs started to melt. I searched everywhere to fine better replacement knobs, but the only ones that i found were not any better than the cheap plastic knobs that came on it upon purchase and did not fit due to the “d” shaped valves being bigger than other brands .  I designed these to fit and printed them on on my Uniformation GK2 with sunlu resin.  havent used them yet but the heat resistance of the resin should suffice.
