I had previously printed a model from GreenNomad:https://www.printables.com/model/327874-voxelab-aquila-x2-detachable-screen-mount 

but the mount was too lose and there was no step so I reverse-engineered that model and made the fitment on my model tighter

warning: please add support on the overhang as it will droop/saggy and it might be hard to fit it to the bracket on the printer, and if you find that mount is sliding in tightly at first don't worry as it should get smoother to fit after a few attach and detachments.

might work on the s2 as it is almost the same printer but I can't guarantee it as I don't have one myself
