A quick remix of @SoloTSi97's excellent FireBoard 2 Minimalist Case, with hood and small internal mangets.

I sometimes run long cooks and although the FireBoard 2 is “weather resistant," I wanted to add a hood to keep rain and direct sun off the LCD. I also wanted to be able to mount it magnetically to make it quick and easy, so I added some small internal pockets for 10x3mm magnets, easily available at Amazon. These magnets easily press into the pockets and seem to do a decent job of holding the FB2 to my pellet grill/smoker.

I also softened some edges and made a couple small tweaks, but the original design is excellent so I had to only touch a couple areas to make it optimal for me.

I printed this in PLA at 0.2mm with 15% infill in the base and it seems plenty sturdy.
