Multiboard Hygrometer Holder

I'm in the process of converting my office wall from HSW to Multiboard. As such, I'm looking for Multiboard alternatives to my old HSW things, especially for cases where the HSW-based thing uses the large connector. I really liked MG Print's holder but wasn't jazzed about the 2-part assembly thing. I found Patryk's remix, which was a single piece, but the ring was just too big to securely hold the hygrometer. Fortunately, MG published a STEP file, so mimicking his ring was simple. Meanwhile, I went with Patryk's idea of a single body, despite needing a tiny support and here we are!

I use these hygrometers from Amazon if it matters. Pretty much all of the round ones seem to be the same thing.
