This is a 3D printed Simac Bowl Lever. This is printed at high temperature from PETG (the same stuff waterbottles are made of). There is no infill, it is printed 100% solid.
Due to the print being 100% infill (solid) the end of the lever frequently warps off the build plate (see photo 3).
I created and own this design, it is not published on thingiverse. These machines are amazing, but there are a few parts that are poorly designed!
No partial refunds because you're not happy with 3D print quality. Full refunds at buyers expense to ship are the only form of refund.
