Trombone Slide Lock v2

Thanks to themathbook for making something with the perfect threads for a trombone!
The only issue I had was that it promptly broke the first time I tried using it. So I have two techniques to fix it.
I beefed up the size in v2 to make it sturdier along the z-axis, and I made a two-piece version that allows me to print the hook on its side for greater strength.
I did adjust the hook sizes a little bit from themathbook to make the hook a little less deep, which fit better on my friend's trombone.
