HyperX cloud 2 replacement clamp - for M3*12 screw

HyperX cloud 2 replacement clamp - for M3*12 screw
Also simplified the geometry and changed it so headphones wouldn't flop so much.

“issues” I've found, allthough I'll use the current version until it breaks:

• Inside may be a bit too tight, which is part of the original remix this model was copied from resulting in the ratched-mechanism not making the intended noise. It sits firm, but the feel is diffrent
• Hole/Indent for cable a bit too tight (internally) for my taste. Also making it universal for both left and right side might contribute to this.

• Changed Screw&Nuthole for M3*12 screw + nut
• Simplified geometry
• Changed the opening side to be straight → less wobble
