New push-to-open door knob to open the sliding door on the Sprinter. (I did actually buy the replacement handle, but it broke almost immediately because the cheesy little plastic tab intended to push on the latch couldn't handle the resistance of the dirty mechanism.)
TPU (orange) sandwiched between PLA (black).
Before this, I was using a simple PLA knob to push on the mechanism, but it was tricky to keep it lined up without slipping off the latch's little metal bar.
Now, the TPU layer grips the bar and can flex as the interface angle changes slightly, and the rigid PLA layers give a nice, solid push.
All printed at 215 °C; excellent bonding between materials. When printed in the vertical orientation, the thinnest parts of the TPU broke along the layer lines very easily, so I ended up printing on its side for better strength in the TPU loop (at the top in the pictures). One side is flat just to reduce the need for support material, and the TPU printed on PLA support just fell apart as I was removing it from the bed.
Works great.
