An attempt to add a heat break to the M3D's nozzle... hoping to find somewhere that can print/mill this out in some sort of heat conductive material once I've gotten to testing if this fits in plastic first. Note that it is a work in progress and may be updated often. V2: usage of M2 screws will probably take too much space so I decide to remove the and go for thermal tape, something like this here: http://www.amazon.com/TapeCase-8810-0-75in-0-415in-Conductive/dp/B007Y7D0NG/ref=cm_cr_pr_sims_t/187-9558189-7288268 Will need some trimming before putting it on though. Also, Be sure the ceramic heating element's wires are bent around the heatsink. I'm not sure how hot these will get yet (and will not be able to test since I'm waiting/looking for shapeways or another source to do aluminum or copper.) nor if they will work well or not. I only know they fit for now. *Note: To use, get 2 of these printed in metal and fit it around the nozzle. forgot to mention that earlier.
