About this 3D model

I have been making plywood spools for sound system cables and needed a bracket to hold the microphones. So I broke out the HeeksCAD and the Makerbot and presto! A mic bracket. Not a complex item: no squid, no whistle, no Bre (http://www.thingiverse.com/thing:5982), but it is tapered to match the taper of the microphone and holds it securely.
