Tippman Cyclone Paintball Hopper adapter the Adventure Force Tactical Strike Titanium Spring Action Team Competition Ball Blaster. It allows you to use a full size paintball hopper for your ball rounds. This part fits perfectly in the rifle's loader slot and locks in with the original locking mechanism. The hopper slot lock on the side allows you to remove the hopper by twist to lock or unlock. There is also an STL without the twist lock and key'd out to lock it in, but I have yet to print one of those. I print this at 20% infill with supports and it takes about 4:30 to print with PLA at 60mm/s. Links to the items needed are below. Enjoy!
