[AMSAT-BB] 3d Printable dual Ft-817 mount?

I took a look at Thingiverse and a couple of other sites, but I couldn't find a mount to attach two FT-817 radios together for satellite use. I've seen them around, so I'm assuming someone's made a public design.

If I can't find one, I'll design my own, but I figured I'd try to find an existing one first.

Thanks. Rich, KD2CQ
