Stacer Cleat Backing Block
Stacer made solid gear, but the small plastics are always the first to go — and the cleat backing block is a regular on our bench. We've made this style of part before and can usually print yours without drama.

Why these break
Backing blocks split under cleat load. Vibration fatigue does the damage: thousands of small flexes add up to a crack at the stress point, usually right where the part clips or pivots.
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 PETG-CF. Carbon-fibre PETG is noticeably stiffer than the stock plastic, so the part holds its shape under clamping force instead of slowly creeping loose.
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.
