Best motorcycle credit card/badge holder

thingiverse

(Since I haven't had to use my badge recently, I've discovered this is a great thing to hold your debit card at the drive-through.) My work requires the gate guards to physically touch the badge and examine it. I'm on a motorcycle, and I don't want to sit there for 5 minutes digging my badge out or putting it away. So I've made a much simpler and more functional badge holder, which is far better than my previous designs. It's one piece, and optimized to print with supports. It's compatible with the RAM Mount diamond ball base RAM-B-238U. It needs 2 common 10-24x3/4" flathead Phillips screws like McMaster-Carr #91771A245, and 2 matching nylock nuts. It does not need washers. It has two small ribs that bow the card up slightly to retain it better. I've tested it for 4 months, and it's secure and easy to use. I've included the OpenSCAD file.
