Let's Split Keyboard Case Lid

I designed a lid to be used with [this](https://www.thingiverse.com/thing:2482218) case for the Let's Split keyboard. It is a friction fit on the case and protects the keys/switches in transport. It has a shelf to only allow the lid to go on so far and some cutouts for easy removal. I used DSA keycaps so if you have higher profile keys it might push the keys some.
