Spare Pyrex auto throw hopper stand?

[MysizeisMAGNUM]

I have a Pyrex hopper for my auto throw A&D setup. I bought a second hopper to ease the hassle of different powders. I know I’ve seen a stand for spare hoppers but I can’t find it to save my life.

For those with multiple hoppers, are you using a stand, where did you find it?

Thanks in advance.

Nobody has multiple hoppers? I’ve GTS this all afternoon yesterday and the struggle is real...
