About this 3D model

This is a fan holder I made with three objectives in mind: - Two open fans. I'm not a huge fan of fan ducts. Some work really well, but having the mouth too close to the nozzle makes it hard to do maintenance on the hot end. - 40mm fans. Those are much easier to find than the stock 50mm fans. - No nuts or bolts (except for those holding the fans). I've tried too many fan ducts and holders, and switching them was a major pain, so I made this clip-on version that just snaps onto the existing bolts. I hope this encourages people to try this design. :) Inspired by scottvader's good results here: http://www.thingiverse.com/thing:125244 I'm insulating with Teflon tape for the time being, but MadOverlord's silicone sock should work wonders: http://www.thingiverse.com/thing:165750 *2013/12/08 update:* The original model could hit the lower bolt on the Y axis sliding block in some cases. That's now fixed!
