BRS-3000 windscreen

As my solo canister stove setup, I use the BRS-3000 stove with a titanium cup, and it can really benefit from a windscreen. First I made one that was hanging from the lip of the cup on three thin aluminum strips. It did its job saving the fuel, but having to remove it from the hot cup after each boil was annoying.
A windscreen attached to the stove that does not complicate handling the pot would be much better. Here’s what I came up with.
The most important piece is the folding support mounted onto the stove. It fits between the stove body and the burner. Unscrewing the burner for the first time is tricky, there’s some glue in the threads. On an older stove, it was possible just by moderate force, on a new one I had to heat the burner to soften the glue and quickly unscrew while hot. Once the glue is removed from the threads, it can be assembled and disassembled by hand.
A heat reflector can be laid onto the supports. For short boils, it is probably not necessary, but the canister may get too hot if the stove was running at full power. It will also help blocking the wind. The large hole allows lighting the stove from below.
Finally, a classic aluminum windscreen is attached to the supports. Notches on the windscreen fit into the little cuts at the end of the supports. It’s a tight fit, so the windscreen won’t accidentally fall off or get blown away.
Altogether, it’s a solid structure attached to the stove, an it does not interfere with handling the pot. It weights 21 grams, but it saves more than that on a 100g canister. There’s somewhat involved assembly and disassembly, but I find it less fiddle than other windscreens with multiple loosely connected pieces.
It all fits inside the pot, along with the canister, stove, folding spoon and few more small bits of the kitchen setup. should fit any pot of similar size designed to accommodate the 100g canister.
Finally, the closed pot goes upside down into a pot cozy that keeps the lid in place, so there’s no need for a stuff sack.
There’s a couple more things worth noting.
First, I’m using a BRS 3000 stove I modified long time ago to avoid the possibility of melting the supports. It work well but doesn’t pack so small, but it still fits this setup. And maybe it’s worth modding the stove especially for use in a windscreen where the supports may get even hotter.
Second, I’m using the vargo bot cup, but with a different lid to save some weight and space. (I still use the original lid with an alcohol stove kit that needs more space.) I got the tip on using a toaks lid here in the forum, but when I got it, I found that it runs a little small. It would be fine for the cooking itself, but it won’t stay in place when packed. I carefully unfolded the rolled edge, and now it fits much better.
Yes, to pack everything into the pot, the supports have to be removed and folded. But it doesn’t take more than few seconds.
I should have added a close-up picture, here it is.
The supports are made of 1 mm hard aluminum alloy sheet.
