Milwaukee Trimmer Spool Cap
We keep getting asked about this one — the trimmer spool cap is one of those Milwaukee 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
Bump-feed cap tabs wear and the cap flies off. Vibration fatigue does the damage: thousands of kilometres of small flexes add up to a crack at the stress point, usually right where the part clips or pivots.
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.
