J-head cooling shield for 30mm fan

cults3d

To be used with Thinkyheads' Prusa i3 Wades Adapter: http://www.thingiverse.com/thing:58451 I have designed this fan-shield specifically for use with the J-head and a 30mm fan. Currently I am still improving small parts of the object so stay tuned! In the end, this cooling shield should also be compatable with other extruder adapters that use a J-head, because the spacing of the mounting-holes is universal. Printed it myself and for me it worked flawlessly after the first try! BUT, there are still a few design considerations I want to apply to the object, and I have to fix three small errors, but they are so small that they won't really interfere with the functioning of the thing. Still a work in progress, I just got Rhino working a few hours ago and this is my first design, I have no experience in Rhino so it took me some time to understand basics just by doing. All tips are welcome! :) Last, this is a Work in Progress, I am still tweaking my design a bit and have to make different approaches to how the air-flow will work the best and make everything actually fit well together. - Marinus
