I want to hang everything on my Multiboard! I couldn't find a holder for my Pixel Buds Pro that I liked, so I remixed the Multiboard Snap with the Skadis Pixel Buds Holder by dtphantom on Printables. Nothing more to say … print, snap and organize your Pixel Buds Pro.
(according to the internet, but dimensions of the Pixel Buds 2 case are the same, so the holder probably also fits these, but I didn't test that)
