37MM front loading fin stabilized signaling round

3D printed 37MM projectiles designed to use with payload, smoke or flare. Regular PLA is sufficient. Print the base plate solid, 99 walls or 3-5 walls with 100% infill. The rest can be printed with 3 walls and 15% infill. The hole in top cap can accommodate a .450 projectile as counterweight. The weighted top cap and the fin will make the projectile fly like a badminton ball. 2323/12/19 update: 2 more head caps to fit 14.5mm M183 lead point detonating projectiles.
