I tried printing with 0,2mm nozzle on smooth PEI and it never went good. The legs are absolutely sharp so the area touching the buildplate is almost non-existant. Every time I tried printing this Keychain with silk gold pla, one of the legs went off the buildplate and it was ruined. Even if I lowered the model under the bed so it had more surface to adhere. Printing it bigger with 0,4 nozzle would probably be okay but you really need to increase the surface and use plenty of brim.
