G2S Universal Effector Jhead Adapter

Adapters for mounting J-head (V5,V6) extruders onto my G2S Universal Effector (spider). http://www.thingiverse.com/thing:1356159

For a single extruder, you can use the cooling fan attached to the extruder's fins (third photo). There isn't room for two fans, so dual extruder configurations will require using a single fan mounted onto the spider instead. The 30mm fan duct (shown) works, but the heat sink fins do run a bit warm, so I've designed a 40mm solution. [http://www.thingiverse.com/thing
