Models are solid, so when you preparing gcode, make sure that you set infill to 0%
I printed those bottles with transparent PLA (It distracts light more than other materials. If you want transparent prints, use PET-G :D)
These prints were used by Poland's group performance at European Cosplay Gathering Season 7, check out their facebook fanpage ---> https://www.facebook.com/MoeMoeRebelion/
