This is the latest iteration of the Cooling Duct for the Makerbot Replicator 2X. (05May14)
It still prints with NO SUPPORTS!
NO MORE SCREWS...IT JUST SNAPS ON AND OFF!!!!! ;)
-Extruders(REV 5) in pictures are for modified custom PTFE lined feed tubes to custom finned heat sinks above custom hot-end using all original Makerbot heaters, and thermistors(Direct Replacement!). Specially made, and tested for FilaFLex, and Nijaflex filament as well as ABS, PLA, TEFLON, and others.
30jun14 - added spacer tubes to download
use at your own risk! ;)
This one has more even flow,
With the addition of the optional cooling tube that cools the area behind the fans where the filament enters the hot-end...no more mushy filament!
Now maintenance is a snap...literally...and it is a snap fit onto the carriage...no more screws! even with the fan attached, it snaps on, and off in seconds making getting to your extruders...a snap! ;)
