Reverse plunger component from a nerf longstrike, slightly modified from original to be a bit easier to print (internal featured an overhang which I've replaced with a 45° incline).
Dimensions were taken from original part using micrometer. Model was constructed in solidworks.
Update:
Part was printed in ABS filament in horizontal orientation. This gave a slight elliptical deformation but otherwise the part came out fine.
When attaching to the existing internals the head split slightly when attaching to the air-restrictor. This was likely due to shrinkage so I either suggest printing the part marginally larger or sanding down the joint to fit flush before gluing.
Once installed the part performed fine and gun fired as normal.
