This model was designed by Makanadumlao, I found it on https://www.thingiverse.com/thing:4851515 (You can find the STL files there). Please stop by thingiverse and show him some love, like his model to support his hard work. The only thing I did was identify a good profile for printing on the Bambu P1S using PLA and Support PLA interface, I am sharing that here.

I found it best to remove the standard PLA support first, this gives the support PLA interface room to flex away from the print. Start pushing the interface away from the underside of the print around the airtag hole, slowly peel it off the print and this thing should fit like a glove for the non-Siri model remotes.
