Getting obsessed with shiny staryu in pokemon let's go, I drew one myself. will definitely print it out with sls machine later. The model was separated into 4 parts to make it easy to paint.

DO NOT PRINT ALL THE FILEs!!! PLEASE CHOOSE ACCORDING TO THE BELOW INSTRUCTIONS

For the core, I recommend to use a 16mm diameter marble instead of printing it. So if you have a marble in other size, simply scale the whole thing to X:16 ratio. And if you find the little clip thing behind is too easy to break, try to print that bodycombine.stl file instead and paint it yourself. the star is also separated into front and back, so you can print it flat the assembly will not be self-holding, try to glue it.
