Microbit Robot Head

As a primary teacher I was looking for a simple way to introduce my younger pupils to the Microbit. I've designed and created a super simple robot head that fits over the top of the microbit, that allows the children to program the LEDs to act as a mouth.

I've included a paper copy as well as the STL and SKP files. Some fo the kids prefered to decorate that rather than 3d print! If you print it on A4 the print out should be the perfect size. This could also prove useful for pupils designing their own remix of the 3d model.
I've included both the SKP and STL to allow you to remix the robot head with the pupils. As long as they don't move the three holes anything goes! I'd love to see some remixes made my you or your pupils!
