Rifle Grenade?

[Dronic69]

Evening All,

These appear to be some type of rifle grenade? Anybody recognise them?

(They also looks like they were made using a 3D printer?)

Thanks
Cheers
Drew

The Fuzes look similar to Belgium ones. But they do look like homemade 3d printed, possibly with blank fire fuze (notice the firing pin ring and hole in the side of the fuze), made to fire for fun.
