Description
This is a 50mm blower fan shroud and mount for the 3-wheeled D-Bot/B-Bot Titan extruder back plate (http://www.thingiverse.com/thing:1833172)
Looks a bit like a lobster claw to me. I haven't printed it yet, but I plan to try it out this weekend. It's not perfectly centered according to the assembly I put together (see images) but if that's an issue once I try it out, I'll update the mount to align it better with the nozzle.
It should be printed on its back with the claw pointing upwards. It might print with out supports if your bridging is dialed in, but could benefit from a few supports.
