Hooks for slat wall / slatwall

Hooks for 3" spacing slatwall. These should be able to tilt in, they don't need to be slid in from the end of the wall. Works fine with PLA against reasonable loads, but if you are hanging something heavy you might want to enlarge the hook or support.

Support needed. Ender 3 v2: 10% support density is fine. Everything else default -- 25% infill but you could turn it up if you need more strength.
