Celestron Nextstar Evolution Hand controller mount REMIX

Remixed the original file by [Spuddy](https://makerworld.com/en/models/2370225-celestron-nextstar-evolution-hand-controller-mount#profileId-2594125) at MakerWorld to reduce the wall height on the left side, so you can still easily grip the mount handle without crippling your hand.

Also included a symmetrical version with the lower wall on both sides, if the mis-matched wall heights annoy you.

Either print with 5 walls or less walls with 15% infil, no supports needed.
