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:1381000]

There are separate adapters for V5 or V6 extruders, print whichever one you need.

I apologize for having the adapter mounting nuts located below the platform, making installation more difficult than I would have liked. But I have added sufficient extra material around these nuts so they can be made captive by folding a bit of plastic down with a hot soldering iron to lock the nuts into place (fourth photo).

Update: Design finalized and tested.
