December 9 update

Added8MM steel ball printed replacement parts, eliminating the need for hardware

Modifiedthe curvature of the battle arena to increase the chance of collision during battles

Required accessories:

BT3×8 round head self-tapping screw

8mm stainless steel ball

Design concept:
1, Each top has its own unique external characteristics, battle head height, mass, and center of gravity. It is not simply about defining the quality of a top by its spin time, which increases the diversity of play and battle fun
2, Equipped with a launcher, it uses a rack and a pair of gear sets for acceleration. The output shaft has an reverse internal spiral, which cooperates with the top's external spiral for launching. It won't easily detach after insertion. After pulling the rack, the output shaft and the top's reverse rotation maintain synchronous movement, and the top's main body quickly spins out
Simple, stable, and easy to install structure, suitable for 3D Printed. A propeller can be added later as a Pull Copter launcher to enhance playability
3, Accessories should be relatively easy to obtain and consistent, so I chose the 8mm stainless steel balls from MakerWorld's beginner maker parts gift pack as the top tip, and BT3×8 round head self-tapping screws as the launcher casing fastening screws, saving users the trouble of finding matching accessories

Initially, 6 different types of tops are provided, including a low-center-of-gravity, interestingly shaped UFO with pointed antennas on its head; a hardcore, clumsy but powerful armored warhammer; and a bouncy golf that imitates the dimples on a golf ball's surface (the function of golf ball dimples is to create vortices, i.e., turbulence, as air passes over the ball's surface, making it fly farther... I heard... it seems to have some effect~~)
The characteristics of each top need to be explored by players one by one

About usage:
Insert the rack, insert the top into the spiral hole of the output shaft, hold the launcher, pay attention to the finger grip position, do not hold it backward, and quickly pull the rack

About printing:
All filament is Bambu Lab official PLA Basic, only the Ice Blade uses translucent PETG Translucent, printed with H2S multi-color, colors can be matched according to your preference. Some tops are also single-color printed
Note: If using other third-party filament or PETG Basic, be sure to pay attention to the filament sinkage rate issue, as it may cause the spiral hole position to shrink too tightly, preventing smooth launching!!! Please experiment with parameter adjustments or post-processing yourself

Installation:
Most tops are two part, with the hexagonal pin in the middle acting as a locator. When installing, make sure to align with the top's external pattern, do not install it crooked. Theoretically, no super glue is needed, and firm pressing will keep it fixed, but it is still recommended to use super glue for fixation! (Due to the UFO's ultra-low center of gravity, the pinhole is too short, super glue is absolutely necessary)

The 8mm steel ball for the top tip can be pressed in firmly

The launcher has snap grooves. If there are no screws, it can be fixed with super glue or tape, but this is not convenient for replacing vulnerable parts like gears

If the internal spiral of a newly 3D Printed launcher and the top do not launch smoothly, place the top in and vigorously twist it in and out to grind it, and it will basically become very smooth

The rip-cord and gears are also designed this way. To ensure durability after wear, I reduced the fitting clearance compared to the initial version, which makes new ones tighter than old ones, but also greatly increases their service life. It will be fine after some use

Lubricating grease can be added to the internal shaft holes and meshing parts of the gear set to extend their service life
