Originally shared 4th June 2012 - Comes with an in-built mount for a 30mm fan to keep your thermal block nice and cool.It's designed to be used with the Huxley Herringbone gear set I did for Day 2.I also re-made a new Idler block with a bit more strength to it than the original.It seems to work just fine, but I'm going to say it's a work in progress until I have done some more printing with it.Made for Day 4 of 30 days of creativity ( #30DoC ) www.30daysofcreativity.com/See my blog for updates and other printing advice - www.richrap.blogspot.co.uk/2012/06/mini-quick-fit-huxley-sized-extruder.html
