I wanted a coin holder with specific coin sections for each US coin type so I don't have to dig around a coin pile. This has a section for loose detritus, a half section for each 5¢ and 10¢, a full section for 25¢ and $1, and zero sections for 1¢, which are completely worthless.
First time I printed this, a friend of mine borrowed my car and it came back warped. He's not the kind of person to warp coin dividers for fun (I wouldn't think. Never thought to ask) so my assumption is that the combination of him parking in the hot summer sun outside his office every day with the nearly 1lbs of coins in the tray caused the whole thing to warp a bit. So my suggestion is print with ABS or park in the shade. The black version's packaging recommends about 15°C higher printing temp, so I'm hoping it won't melt as quickly as the blue stuff did. Color shouldn't matter since it's going in a dark cavernous armrest either way.
Probably best to print with ABS to fight hot-car-syndrome.
