About this 3D model

I wanted to use Carl's Alu block with the stock Flashforge Creator X extruder set up so I made a set of spacers to get the filament to line up with the thermal barrier. This is the part I'm referring to:http://shop.raffle.ch/shop/alu-dual-cooling-block/ The other option is to print or purchase a feeder for the makerbots but for now this is my solution. I am still deciding on what to do about the feeder. I might just spring for the 3in1 machined feeder since it is very popular.
