This Instructable is for getting a 3rd supporting hand when you need to fix or clean the feeder on the Ultimaker2 3D printer. I've experienced difficulty keeping the motor in place when reassembling the feeder mechanism on the Ultimaker2. Typically I need one hand to screw, one hand to hold the things together, and one more hand to hold the motor in place. With Sugru, I need one less.
Step 1: Step 1: Unscrew Cover Casing
First you unscrew your cover casing of the feeder engine in the Ultimaker2, which will make it look like in the picture.
Step 2: Step 2: Apply Sugru
Then you mold the sugru and apply it as support structure underneath so the motor doesn't fall down when you unscrew the feeder parts on the backside of the Ultimaker2. You now need a hand less to reassembly the feeder mechanism on the back! (which is handy if you're a human being with only two hands)
