Fender Control Knob
We keep getting asked about this one — the control knob is one of those Fender 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
Control knobs crack at the splined pot shaft. The original was moulded thin to save cents at production volume. That was fine when the plastic was fresh — years on, there's no margin left in it.
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.
Many plastic parts can be recreated, repaired, redesigned, or printed, depending on size, load, heat, material, and available samples. Bring in the damaged part or upload photos for assessment and we'll give you a straight answer before any work starts.
