Standing Desk Pen Holder

If you happen to have an Ergotron standing desk and a Datalogic Gryphon barcode reader, this is the standing desk accessory for you! This project started with a slanted keyboard tray; while I typed the mouse would shimmy to the edge of the tray and fall off. I started in Tinkercad with a little spacer to level the tray and built from there. The post-it caddy doubles as a phone holster - provided you also happen to have an iPhone 6 in a case. Being named Dave isn't required but doesn't hurt ;)
