Blanco Cooktop Control Knob
We keep getting asked about this one — the cooktop control knob is one of those Blanco parts that fails long before the rest of the unit is done. We've made this style of part before and can usually print yours without drama.

Why these break
Cooktop knobs split at the D-shaft. Heat cycling is the killer here: years of expanding and contracting work-hardens the plastic until a routine bump becomes the final straw.
How we reproduce them
This is a quick job on our end — we take dimensions from your old part, adjust for print tolerances, and run a small batch so you have spares for next time.
We print these in ABS. ABS matches the look and feel of the factory plastic, takes a sanded or textured finish well, and handles cabin temperatures without complaint.
As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
