skin scuba 3 3D print model

hello again and thank u for early rely. i download the file. i'm a jewelry craftwomen and i want to use this skin scuba as a pendant. Yesterday, i went to 3d print company and told them to scale the item to 5cm lenght. they told me that when they scale to 5cm, the small parts cant be print because off the thickness like palletsh. They told me that the drawer of this file can arrange the thickness of the smaller parts. Smaller parts must be bigger then 0,5 or 0,6mm(50/60micron) for to print. is it possibler for u to scale the object to 5cm and control the thickness of the small parts when u scale it? thank u in advance
