Masport Mower Primer Bulb Surround
Spares support for older Masport products is patchy at best. Reproducing the mower primer bulb surround locally is often quicker and cheaper than the hunt for old stock. With your sample on the bench this is a realistic reproduction job.

Why these break
Primer surround cracks and the bulb falls inside. 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
This is a quick job on our end — we take dimensions from your old part, adjust for print tolerances, and run a small batch so you have spares for next time.
We print these in ABS. ABS matches the look and feel of the factory plastic, takes a sanded or textured finish well, and handles cabin temperatures 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.
