Ticket Holder Rack
 

A ball-less ticket, check or order holder rack for easily sticking orders in a restraunt or a bar. contrary to commercial products, this one doesn't use the ball - gravity mechanism, but a simple Moritse that "folds" the paper so that it doesn't fall off.

It is easy and quick to insert and pull out without having to keep a constant eye contact. just slide the check/order into the holder.

Mount the rail to a wall using a strong, mounting tape available in any hardware store (if there will be demand, i also have a version with holes for screws). 

This holder rack, printed in PLA, has been tested repeatedly with more than 1,000 reciepts without any meaningful degradation. it still holds out well enough! PETG will probably be better, but i haven't tested it yet.
Note - This has been tested in a real world enviornment in a cafe, but not adjacent to the hot line, so it wasn't exposed to high heat degrees. if you need one next to your ovens or grills, buy the commercial metal one.
