Robo 3D clear case mounting clips

Mounting clips for holding my clear cases on our Robo 3D printers.
I bring the printers to schools and these cases keep fingers out of the moving, hot printers and keeps cold air off the prints while allowing for great viewing. The clear cases are very easy to lift on and off.
The "Part A" is glued to the Robo 3D case and the "Part B" is glued to the clear plastic case.
Printed with 100% fill using ABS.
