I designed this set of miniature handheld keychains  as a  small nod to the portable gaming I grew up with. 
 

Clamshell models: the two folding designs use a filament hinge. Push a piece of filament through the latch, trim it flush, so the lid can open and close.

Per-console profiles: each handheld is its own print profile, pick the ones you want.
