Can this part be made again?

EligiblePhysical replacement

Plastic synth key: not safety-critical. A single key is expected to be under 205 mm long (inferred, not measured). Surface finish and the hinge/spring features make resin or injection-quality printing advisable.

Candidate materials: ABS-like resin, 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.
