No label defined (Q39519)

I had been using a variant on the original mendel hot end ( http://www.thingiverse.com/thing:2018 ) and was constantly getting heat transfer up to my (sadly) PLA printed extruder parts. These parts were actually deforming a little under the heat. So I redesigned to fit my needs. This is a new hotend design borrowing from from makerbot's MK5 extruder (see http://www.thingiverse.com/thing:3290 ). It has a nicrome wrapper cylindrical solid aluminum core and fits into a PTFE sleeve at the top which allows it to be used with the original mendel X carriage. Additionally it can be used with the MOSFETs on the mendel extruder controller board and doesn't require large clicky relays. ;) It makes use of the MK5 nozzle and thermal barrier tube that you can get easily from Makerbot Industries storefront.
