Low Profile "Snap-In" Arduino Uno Holder V3

Here is version 3 of my Uno holder. I broke too many of the end clips so I redesigned all the things I didn't like about my earlier versions. Here is my newer version to attach/remove an Arduino Uno. This mount uses three small 4-40 size bolts to attach it to a project box. PETG or ABS is recommended as the clips need strength and flexibility. PLA was just too brittle.
