3D printable slingshot pouch and practice ammunition.
Print the pouch with flexible TPU/TPE filament.
Print the practice ammo with a more rigid filament, preferably PLA as it is the heaviest. Print ammo completely solid and with support. I recommend gluing the pieces of the rock together.
After the pouch is printed, tie straps made of paracord or a rope of personal preference to each end of the pouch. Straps should be around the same length as your arm.
Ample practice is needed to gain consistent accuracy, so do not expect to learn quickly.
The sling can be used with rocks as well. Choose smooth, well-balanced rocks similar in size to the included practice ammo.
