Ludwig Control Knob
We keep getting asked about this one — the control knob is one of those Ludwig parts that fails long before the rest of the unit is done. With your sample on the bench this is a realistic reproduction job.

Why these break
Control knobs crack at the splined pot 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
The process is simple: drop the part in or send clear photos with a ruler in frame, we confirm fit details, and print replacements — often with a little extra material where the original always cracked.
We print these in ABS. ABS matches the look and feel of the factory plastic, takes a sanded or textured finish well, and handles everyday warmth 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.
