Amazfit GTR Smartwatch recharger stand
This is my personal interpretation for a simple-to-print, nice and stable stand for the rectangular version of the Amazfit GTR smartwatch charger (maybe further Amazfit models could share the same kind of chargher).
I placed 4 small gaps on the lower side to acceps some kind of adesive foot; or you could do like me, applying two stripes of soft linear gasket (Please look at the enclosed picture).
