Commodore Coin (for shopping carts) full color

thingiverse

The wellknown (well, within the scene) Commodore Coin, now doublesided in full multicolor (with the top beak of the chickenhead being blue on both sides!). It's a coin with the Commodore logo, f.ex. for shopping carts (it's a Euro thing, don't ask! ;-) At 23 mm diameter and 2.1mm thickness, this fits in shopping carts that want 50 Cent coins, carts that want 1€ coins - and carts that accept both. They're surprisingly durable and last years kept in your wallet, even when printed in PLA! The perfect giveaway for the 3D color printer owner: Prints quickly, needs only 28cm of filament in total, tiny waste tower, looks good and is actually useful! ;-) Here's a version with manual colorchange for single-color printers: https://www.thingiverse.com/thing:3661100 Edit Feb 2020: I added a V3 version with a lifted center so that it now has a relief on both sides! It was quite tricky to get it to bridge nicely, I did this with a modifier, doing some bridge-flow testing that showed that a factor of 0.3-0.4 looks best - that's all included in the .3mf file, so I recommend you use that instead of the lifted white STL! It also prints faster now, cause the center is all white - but now it isn't suited for a transparent base color anymore, I still recommend V2 for that!
