This is a spare part for the mechanism under the metal handle in a Bravilor Bonamat pump thermos I designed after one of these broke for the second time at my regular morning coffee spot.
There's a lot of empty space and sharp corners on the original part that serve no purpose, other than an originating point for fractures and cracks, so I took the liberty of filling them out.
Print on it's side with supports for the hinge to get maximum strength out of your layer lines and use a filament you'd trust to handle the load.
Installation instructions:
- Separate the top lid from the thermos body by pushing out the hinge pin with an Allen key, a punch, needle-nose pliers or something else of suitable size
- Remove the bellows by turning the round central part approx. 30 degrees counterclockwise
- Unscrew the lone screw in the middle of the spout cover
- Release the four latches around the perimeter with a flathead screwdriver
- Be careful about the spring: Depress both of the buttons on the spout cover and pull the internal cover out of the lid
- Remove the screw in the hinge for the handle and maneuver the handle assembly out of the hole in the lid
- Separate the broken lever out of the handle assembly by pushing out the hinge pin
- Replace the lever and put the lid back together by reversing the steps above. I pushed the hinge pins back into their place against a workshop table.
