The Filament Fuser Block enables you to securely fuse two ends of 3D printing filament together in roughly 10 seconds. With this tool you can recycle leftover filament, extend the length of your filament spools for long prints, and add color changes to your prints!
The printed parts enable you to safely hold the heated block under a hinged guard, and clamp everything to the side of a table. It works on 2.85mm and 1.75mm filament in any printing material. The Fuser Block is controlled by plugging the (3) two-pinned connectors into your existing 3D printer controller, so you can precisely control the temperature!
These 3D printing models are shared here for free, but to complete the assembly you'll need the associated hardware kit from the EngineerDog Store here: https://engineerdog.com/store/filament-fuser/
Complete assembly and use instructions available on 3D Printing.com here: http://3dprinting.com/how-to/fuse-filament-home/... See image attached for recommended print settings

Update: Now included is a printable jaw cover that fits on standard 6" slip joint pliers. Using grooved pliers to squeeze a freshly made warm joint with as it cools helps compact it and further strengthens the bond.
UPDATE 1: This device is intended to be controlled by your existing 3d printer controller. This is super easy for a reprap printer, but difficult for some commercial devices. My recommended solution for a stand alone controller is to get the cheap complete reprap ramps kit and just use it for this purpose. (After you get it setup you wont even need to connect it to your computer!)

UPDATE 2: New part "Clamp Face V2" is intended to replace the original clamp face. The new one doesnt require a nut to do the job!
