This is a laser cut shock mount for a SE1000A condenser microphone.It minimises mechanical vibrations coupled into the mic from the stand. The assembly is more or less self explanatory but I put detailed instructions on my blog. http://www.jens-kaufmann.net/blog/2010/05/05/diy-lasercut-microphone-shock-mount/ It can be mate from MDF or PMMA (6mm) on any CO2 Laser with 40W or more. I personally used a epilog system. In addition to the laser cut parts you will need: -a couple of rubber bands (nothing special) -1 M4 bolt, 15mm thread -1 M4 washer, and -1 M4 hex nut And a M6 bolt to mount it. Have fun.
