This is a clip-on shield for my keyboard to prevent my cat from sitting on it. It is designed to fit a WASD Code V3 with an aluminum case, and it will need to be modified to fit another keyboard.

I've included the FreeCad project so it can be customized as needed for your personal keyboard. Basically you'll just need make the clip the correct size and make sure the ramp touches the ground properly. To make the prototyping process faster I just printed very short versions (1cm) until I got the right shape. Prints standing up, with a built in brim to prevent curling on the edges.

Print standing up with supports!
