NASA worm keyring keychain

Simple design with very satisfying effect. Printed with two colours TPU looks great :)

Printing suggestions:

• scale STL to fit your needs - I have noticed that in some cases its necessary to scale model 130% in Z axis to look better 
• use your favourite slicer to prepare gcode with colour/filament change
• make sure that both halfs of the model have enough layers to have a solid colour on top
• prusa slicer 2.5 automatically detects logo and suggests two colour print
