Blackstone Griddle Cover Support Pole

I have a Blackstone griddle and the cover works great, other than it sags on top right to the cook surface, leaving rust spots. This is to support the cover from underneath to prevent water from pooling on the surface. Sits about 8 inches tall.

May want to print in ABS or PETG for outdoor durability. I'm going to test PLA under the cover and see how it handles the heat. I'll probably end up having to make one in PETG.
