About this 3D model

MK7 is the newest version and it works as intended. This is a fan shroud for the Printrbot Simple Metal. It uses a double width fan. I recommend printing it with ABS, I printed it using PLA and as I have found in the past as long as the fan runs it doesnt warp. Do that only if you want a melted fan shroud though. After printing, break away all of the support material, drill out holes, tap holes. Important: break out most of the smaller diameter part of the inner extruder tube section . Update: I have been printing with this shroud for a while now, over 100 hrs with it printed out of PLA. No issues and great prints.
