SmackBack Sentinel Self Resetting Target

SmackBack Sentinel

Meet the SmackBack Sentinel — the self-resetting target with attitude.
Designed for Nerf and airsoft enthusiasts who crave more than just static bullseyes, this mischievous little sentinel bounces back after every hit thanks to a clever weighted base packed with BBs. No springs, no electronics — just pure physics and personality.

Its stylized mask face isn’t just for flair — it dares you to take your best shot. Whether you're dialing in your aim or hosting backyard skirmishes, this bobble-style target adds movement, challenge, and a whole lot of fun to your setup.

• 💥 Self-resetting via gravity and weighted base
• 🧠 No moving parts or assembly required, only requires a handful of metal BBs
• 🎯 Perfect for foam darts, airsoft pellets, or low-impact projectiles
• 🖨️ Easy-to-print, support-free design
• 😈 Comes with attitude baked in

Print one. Print a dozen. Line them up and let the showdown begin.
 

🎯 Your aim just met its match. 🎯

✨Printing Guide:

• Very simple, no supports, 3 wall loops for added Strength.
• The target uses Variable Layer Height to get the base sphere to be as smooth as possible.
• There is a single pause near the end (there is a picture of the sliced pause) of the print were you must dump in a handful of metal BBs, do not use airsoft BBs! Put in as many as you can without overflowing and hitting the nozzle when you resume the print.
• If you don't use the 3mf provided, make sure you use a VERY LOW gyroid infill, 3%! 
• The model is scalable to a point. you need to make sure your weight ratio of printed filament to loaded BBs keeps the center mass at it's base.  I've gone down to 60% and it still worked.
