Pull ring ignitor for fireworks like smoke bombs, firecrackers etc..

Glue (i use hot glue) 2 matches together and attach/glue them to the firework, then glue the fuse to the matches touching the part that ignites in the middle of the 2 matches, cut off some of the striker from the match box and glue inside the 3d printed part, add some string or wire, push the 3d printed part slowly on-top.

NOTE: i used TPU and never tried PLA or something tough yet but it should be ok.
