NERF Guns are popular all over the world and used for a bit of harmless fun at home, around the office / workplace and outdoors. It provides a new sporting / competitive dimension to NERF Gun fun.
The target itself is a moving one piece print with hinges. The second part is a small flat strip of PLA that is used as a return spring. Both parts only uses a bit over 60gm of PLA at recommended setting (including Raft). As an alternative to printing a PLA spring you can cut a similar size strip of flexi / springy plastic from an old plastic container of some sort.
Allocate a specific number of NERF darts to each competitor and score their hits. This target makes it easy to see hits as it is spring loaded. You can hear a hit and see it spring back... then it pops back up and into place ready for the next shot.
The target is easy to mount. Either use a couple of screws into a block of wood, a wooden bench, shelf or fence then slot into place. This makes it easily removable if you want. The alternative is to clip it onto a bench, table or shelf using a large bulldog clip.
This is a great fun alternative to the usual 'human targets' NERF Guns are commonly used for... and it can become very competitive.
Please refer to the print settings and images for additional information.

2 Shells / 20% infill minimum / PLA
2 Shells / 20% infill makes the target adequately strong but, if you're happy to use a bit more filament (because you expect you'll use it a lot) increase to 3 shells and 30% infill to make it really strong... PLA is tough so it stands up to hits very well.
Raft is recommended for easy removal from the build plate.
Do not scale this down as it will affect the internal clearances used for the hinges. At standard scale the target measures 172.50mm x 116.50mm.
Remove the raft, insert the flexi spring and mount....
After Raft removal you need to insert the PLA flexi spring. This should easily slide into the thin slot in the lower centre of the target. Once installed just fold the target upright, mount it and you're good to go.
You can use a strip of flexi plastic cut from an old plastic container as an alternative to using a printed PLA flat spring. This will change how springy / flexi the target is and its rate of return. Other plastics may in fact be better (PLA is hard so it snaps back quickly. Other types like polypropylene are softer so still return well but slower).
