Oculus Quest 2 Koss KCS75 Headphone Mount for BoboVR M2 with servicable clips

Stuff you will need:

• Two M3x4 (@5mm) Heat Inserts (Goes into the holders)
• Two M3x6mm screws (Secures holders to the L-Ears) M3x8mm works too.
• (Optional) Two M3x20mm Screws  
• (Optional) Two M3 Nuts

How to Print it: 

• The L-Ears can be printed in PETG+ or PLA, your call. I used ASA. 15% infill, Gyroid. 
• Add supports in the screw hole. 
• Copy-paste it to your favorite slicer and mirror it. Print flat side down.
• The holders absolutely need to be printed in PETG/PETG+, 100% infill, (or +4 wall), add supports in the hole… Be sure to print a few extras as they can get deformed or crack easily. Then you'll have spares. I used clear PETG+ in accordance to @Rygar1432_36648's awesome guide. I recommend it as the holder will be super strong.  Print with the forks pointing up. 
• Print a jiggy. Trust me on this, it'll save your fingers later. Doesn't matter material, just print at least one. I recommend printing with the holders. 
• (Optional) Pin can be printed in PETG+ or PLA, same setting as the holders.

How to Assemble: 

• Get your jiggy, and plop a holder on, forks facing up.
• Insert a 1.5mm allen key or similar into the middle to eject the support. Toss the support, do not eat it.
• Place the holder into the jiggy, forks facing down, and give it a heat insert until flush
• Plop a Koss driver into the holder
• Use the 1.5mm allen key to eject the support from the L-Ear
• Assemble the mounting hardware from the links below
• Insert a M3x6mm screw into the L-Ear and attach a holder with headphone driver.
• (optional) If you're like me and don't have a M5x20 screw, but have M3's, you can create your own M5. Print the bolt body, insert a M3 nut. Then thread the M3x20 into it. Et Voila, free M5x20 security pin. 

This kit is to be used in addition to @FortinMike's hardware. Or the mounting system by @DWO_261266. Great designs guys.
