This is an addition I made to the Screwable tighter Bambu Lab AMS stackable stand by @Fredster. I really liked the model but I wanted to do something to top it off so that the AMS small stack didn't end so abruptly with no purpose for the top screws on a shorter AMS stack, so I designed this.

I remade the original design in Fusion 360 as just an arc instead of the ‘X’, though I tried to get it as close to matching as possible so everything went together nicely. In my version the hex pattern is just on one side since you won't be able to see it anyway.
