The hole for the steam knob stem was pretty large and would allow for the wiggle of the knob. I designed this insert to reduce the hole size from 25mm to 20mm to help reduce the unwanted bending on the knob while turning.

 

It was printed at 0.3mm with PETG. I recommend all walls and a slightly lower flow rate to get everything fitting right. The piece should snap into place, and now the steam knob will stabilize a bit better.
