Rectangular mini hygrometer spool adapter

I found a bunch of models to insert the cheap round hygrometers in the middle of spools but none for the rectangle ones which everyone seems to use on dry boxes. I guess they are matching the shape of the container but the rect ones are half the price per unit on Amazon and still smaller than the middle of a spool. So I remixed this adapter for a round one to accept the rectangle instead. Credits to @Achimque v2.3 for the original adapter. Enjoy!V2 should print cleanly without supports or string
