Coin Holder - Compact and lots of space
I recommend using the "bigger" trays for the 11 bottom trays. You must use the "top" tray for the 12th tray, it does not have the pins so the lid fits nicely. I will include the first design of the tray as well if you decide it fits your needs better, I found it hard to remove coins from it.
I printed everything at .2mm
Print cap with threads facing down and support angle at 55%, build plate only.
