Can this part be made again?
EligiblePhysical replacement
Hand-operated cabinet button, not safety-critical; the shaft rides in a bushing and presses a switch, so it needs a tough material and good surface finish.
Candidate materials: PETG (confirmed by test-fitting).
EligibleSTL / FreeCAD file
Can be offered as a printable file and an editable FreeCAD model once the measurements are verified.
