CatCoin Challenging print on FDM

If you bored to print Benchy bottoms for Z height check you can print this one too.

You can print this with only a perfectly dialed in printer so it will be a challenge, but worth the test.

You can use this to test various things like:

• Z height (check if the cat face or pawn is squished or dragged by the nozzle). Check how the bridging works.
• Bed levelling - mesh check. Spread them on the surface, print only the 1st layer, check the print, look for differences. 
• Elephant foot - brim distance - print one, check if you can remove the brim easily.
• Bridging - check the difference with normal and thick bridges.
• Fine details - check the cat face on both sides of the coins. Check the text, if you can read the Meow - you're good.
• Filament state - you can't print it with a wet filament correctly.
• Retraction - the fine details are ruined with wrong retraction settings.
• etc.

The default size works only with 0.4 (or smaller nozzles). Bigger nozzle might not able to draw the cat face correctly.

And you can also use it in shopping carts instead of real coin (sized as a 100 HUF coin) - as long as it fits the size (works well in Hungary).

The plan is coming from a colleague of mine, he just wanted to print a coin - turned out it's really good for above tests as well…
