Universal flexible bumper for MBot2 / Mbot Neo

A flexible bumper for the Makeblock MBot2 (MBot Neo). It fits the front and the back.
The design features flexibility in all directions and rounded corners, which is great when the bot is driving against your furniture or walls.
Although the bumper is flexible, it is still quite sturdy and will not break easily.

The bumpers are fixed with 2 screws on each side. Please see pictures, which screw holes to use for font and rear.
You can use M4 screws (either metric or self-tapping). Scew length should be 6 to 8 mm.
I recommend flat head or lens head screws, like shoes in the picture.

For best results, print with PETG, use 2 solid outer shells and 30% infill (rectilinear 45°).
