3in1 Universal Extruder Upgrade

This extruder feeder upgrade replaces the stock mechanism on the following 3 Makerbot Printers (It also fits Wanhao/FlashForge/MagicFirm printers which are similar to the Rep1): Replicator 1 Replicator 2 Replicator 2X More information can be found at www.devilsinthedetails.ca You can download and print the housings and install hardware yourself or order a kit manufactured from billet aluminum and PEEK engineering polymer for long life and durability under extreme temperature (PEEK performs well up to 480*F so it will continue to work if you choose to print ABS/Nylon which requires higher temperatures). Here are some of the features: 1) It employs a bearing to provide even force to the filament as it varies in thickness. This force applied is easily adjustable without the need to replace parts or disassemble anything. 2) It re-positions the stepper motor rearward so that the gripper wheel can engage the flat on the motor shaft. No more need to file the shaft yourse
