This print is designed to work with a MMU. You need silver, red and black filament.
Red and Black are only used on a few layers, so not so much filament to waste. The rest is done in silver.
Part 1-3: silver
Part 4: red
Part 5: black
0.2mm layer height
Printed it in PLA and the first version survived for 3,5 years with heavy usage (this one should be even more robust)
Best if you print directly more than once at the same time.
If you do not have a MMU use this one https://www.prusaprinters.org/prints/139714-hyundai-n-logo-keychain
