MODO Utility blade key ring

Contributions of both form and function were considered, among a rescue whistle and a rule, the first design proposals were 3d printed and aspects of use were reviewed and refined. whistle was ruled out for reasons of hygiene and because it would greatly complicate the printing. We worked on the closing system and finally we made printings in different types of 3d printers to validate the manufacturing files.

The result, a keychain - knife with an auxiliary ruler in centimeters in 2 pieces, that can be replicated in any 3d printer and works with commercial "Utility Blades" spare parts.

we hope you enjoy it!
