3D model description

A retractable keychain/badge holder with moving planetary gears.

This is a variation of my other design. Beside the look, the difference is that it is significantly smaller and lighter and assembly is much easier.

Other non-printed parts required:
- a clockwork spring ~3-4mm wide (might be taken out from a cheap mass-produced retractable keychan/badge holder)
- a nylon string ~1m length
- 6 m2x12 screws
- 4 m2.5x8 countersunk brass screws

If you want one already printed, assembled and tested, you can place your order on etsy.com here :)
