It is remix of this model https://www.prusaprinters.org/cs/prints/65809-apple-watch-stand from Aeonfly (https://www.prusaprinters.org/cs/social/52370-aeonfly/about). I re-mixed it as a stand not only for Apple Watch but also for mobile phone wireless charger. My wireless charger (for iPhone) is 10cm width and 7mm height. It is necessary to put supports under watch stand, see my .3mf.
