I created coasters with Super Heros Logos.
Fore some coasters a 0.2mm Nozzel might be the better option.
The size is 100 x 100 mm and 4mm thik. I added a 1mm cork Layer on the back of the coaster.
Thanks to the cork, the coaster on the table is not quite as slippery.
I bought 1mm cork tiles on Amazon.
These are the tiles I bought, they are Self-Adhesive.
