The small plastic piece that holds this printer door closed snapped off some time ago. Tape has been securing it for a while now, but Sugru might be able to do it better.
What you'll need:
A narrow tool for shaping (I used a tool for shaping clay, but even a butter knife would work)
Step 1: Place the Sugru
I put some Sugru right on top of the base of the broken-off piece, extending upward. I ended up using more than I expected to reach the next piece.
Step 2: Mark Bend
Here, you can see where the Sugru came through the hole in the piece that secures the door. Mark where it needs to bend or bump.
Step 3: Shape
I bent my Sugru piece where I marked it in the previous step. I imagine adding a small bump would also work, as long as it still fits through the opening in the printer wall.
Allow the piece to cure for 24 hours.
