Thank you Tom for the suggestion, this case is used to protect the screen and battery of the NewbitArcadeShield. Make it better adapted to the classroom teaching scene.

This print is designed to require no support. It takes 1 hour to print. No screws are required. The upper and lower shells are fixed with a fixed structure similar to that of a toy 4WD vehicle.I used a Bambulab 3D printer and the assembly results are very good.
