Naolia Sea Fightress 3D print model

hello, i download the file. Yesterday, i went to 3d print company and told them to scale to 5cm hight. i'm a jewelry craftwomen and i want to use this model as a pendant. thickness is very important becouse i use valuable metal so it costs very expensive. When we scale the object to 4,5cm, it weighed too heavy for a pendant jewelry. we make it 2,8cm long and it weight about 9gr. the weight is ok for a pendant but i need 4,5cm hight with about a 9-10gr. then the 3d print company drawers told me that the drawer of the object can make the scale in the most straight way. can u please make an update of the object to scale for 4,5cm and get a little bit thin. and also the thickness off the smaller parts must be at least 0,6mm(60microns). i'm looking forward to updates. thank u in advance
