Nerf chinese clone jolt muilt dart kit

STL version:
V1.2

File Description:
The original intention of this design is for all kinds nerf dart, which can ensure certain performance and increase playability at the same time; So far, this design is compatible: all kinds of 13mm dart, 22mm rival balls, mega dart and u dart;
It does not mean that you have this design. The STL file can only be used for personal use, or it can be made at the printing cost price for up to friends. This design or the derivative design with non schematic modification based on the structure of this design can not be used for commercial purposes;
Rival balls, mega darts and u darts can be used to pull out the dart nest. The front plug of the flint can play one by one. After inserting the nest, it has a 160mm linear dart nest, which can realize more playing of the rear plug. 13mm darts can be combined at will, and the length can be less than 160mm.
At present, I use the superposition of the original spring or gecko 9kg (1.5 * 20 * 110) spring, and the four short darts can reach 110fps;

Bill of materials
M2.6 * 8 flat head self tapping 6 tail covers and hammer for fixing. It is recommended to replace the original screws. The original screws are a little rusty
19 * 1.5 O-ring 1 tail cover airtight
M2 * 15 pin for tail cover rotating shaft
706 silica gel for air tight
28mm EVA damping pad for racket head buffer
Gecko 9kg spring as a main spring
The length of inner tube od16mm and id13mm is planned by ourselves. The theoretical calculated length of corresponding cylinder is 270mm, which should be less than this length, which depends on the air tightness and spring (about 100mm is built due to the air loss of variable diameter magazine)
