Sturdier Low Profile Mic arm

Huge thanks to @NicolasB_1901586 for the original model, i had to make some adjustments for my use case, these may or may not work for your printer if your tolerances are better/worse, I printed these on an ender 3 and cr10, both calibrated by califlower. Tolerances mostly same as original, 0.5mm with a few exceptions.

Changes were made primarily to accommodate for printers with slightly bigger tolerances, ease of use, and to allow for printing with lesser infil/walls to reduce weight and printing time while still maintaining toughness

List of changes:
Added surrounding support on clamp (body 1) to wrap around arm for sturdier arm pivot support 
Added texture to clamp screw (body 2) for more grip
Added teeth to pivot joints (body 4,5) so it doesn't easily slide
Expanded pivot joints (body 4,5) from 20mm to 20.5mm to accommodate for earlier teeth
Revised bolt threads (body 6) for hinges for printing tolerances
Enlarged bolt head line, deeper for use with flathead screwdriver (body 6)
Made nut (body 7) for bolt (body 6) slightly thicker
Added hex grip for nut tightening tool (to tighten body 7)

I also remixed the original's tool for the nut and added a grip, and made an end mount for at2020 mics, In the photo I made a shorter version of the new arm and epoxy'd it to the original so I didn't have to print a whole new arm to add the pivot teeth

Suggestions for future improvements:
-Further strengthen clamp, overtightening can quickly lead to expanding the clamp
-To add same teeth to underside of bolt head of body6 so you won't need screwdriver to keep it from turning
-to make tool for other nuts, I'm personally fine with using my pliers
-to add grub screws perpendicular of each pivot joint, these are commonly used in monitor arms to control turning, may be redundant with the nuts tightening mechanism but i personally wouldn't buy a monitor arm without one, so might be beneficial to implement them on the mic arm, requires you to make small grub screws or buy metal grub screws so too much hassle imo
-Hirth Joint pivots? maybe fun to explore using these but would definitely be a hassle to have to unscrew the bolts entirely just to move a few degrees.
-Expand bottom hole of primary arm body3 so same thick nut can be used for the threads on the clamp and the threads bottom of the arm, maybe this wasn't done to ensure support on the pivot? i left it as is because I'm fine with the smaller nut personally, but it is a tad bit annoying 
 -Some form of self locking nut alternative for people who want to keep the arm in place for a very long time
