Whitco Window Winder Handle
Whitco made solid gear, but the small plastics are always the first to go — and the window winder handle is a regular on our bench. With your sample on the bench this is a realistic reproduction job.

Why these break
Winder handles snap at the spindle square. The factory part is made from styrene-based plastic that loses its plasticisers over the years. It gets glassy, then one warm day it lets go under a load it used to handle easily.
How we reproduce them
Bring in the broken part and we'll reverse engineer it — usually with a design tweak that addresses why it failed in the first place, not just a copy of the weak original.
We print these in Nylon. Nylon is slippery and fatigue-resistant, which makes it the right choice for parts that pivot, slide or flex thousands of times.
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.
