Some simple “Kirby” earrings (might work as keychain as well → would use PETG instead of PLA in that case).

Please use my print profile and a 0.2 nozzle to get a decent result.

Print on textured plate to have a nice surface finish.

The colored layers are only 0.5mm in total to keep down printing time.

As a result of this you might see black shadows through bright surface colors from black top layers (1mm in total).

If you like to have brighter colors just change size/ratio of assembled objects as you wish.
