Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4284182.
This is a remix of my second version https://www.thingiverse.com/thing:4284169 but I've added a convex bottom so that it can recess for a tighter fit on some gas applicances where the valve protrudes.
This one will require a bit of bed survace support in the center. Also add a good brim or raft to help keep it stuck to the bed.
Print in ABS or other outdoor suitable plastic. Fits standard gas valve keyed shaft found on most BBQs or outdoor gas appliances.
I would recommend a bit of acetone smoothing if printing in ABS.

Please Post your Makes. I would love to see how they turn out.
Thanks, Enjoy!
