Super Simple Filament Swatch

I know there's already plenty of other designs out there, but they were all a bit too big and fancy for my tastes, I wanted something small and simple that would print out nice and quick - less than 10 minutes.

These are 15mm x 30mm, just big enough to get a "flavour" of the colour.
There's a 5mm hole so they can be threaded on to a bit of string or whatever.
I keep them on a "12cm Wire Keychain Cable" (often used for luggage tags), cheap and easy to buy from the likes of Amazon - I bought a pack of 20 for 4GBP!

It fits easily into a trouser pocket (or purse), and there's no sharp edges to worry about, in fact it also doubles as a fidget toy and a baby's rattle...

"I would buy you some filament for your birthday, but I don't know what colours you have" - SOLVED.

"Sure, I can print that for you, what colour would you like?"
"I don't know, what colours do you have?" - SOLVED.

I've given my girlfriend a complete set of her own, life changing.
