This lever adapter for the Gaggia Classic Pro espresso machine slips over the existing steam knob. The Idea is to not disassemble the existing one.
I printed it with PETG, because it has a little bit more thermal resistance, is a bit fexible so that it does not scratch the original knob and the screw is a bit softer than a PLA one.
If you want it as solid as possible than use more than 5 Walls.
