Since I'm still waiting for my arrows from Aliexpress, I became really impatient and had to create my own to test my crossbow.

I know it's not the best arrow on the market and it doesn't have a metal tip, but you can make your own plastic arrow by yourself! You can see how strong it is in these GIFs. In the penetration atempt it was the bambu refill hard cardboard.

Assembly Instructions

After printing the arrow (PET-G strongly recommended) and the arrow fins (TPU), you can assemble them together.

1. Put the fin with the hole into the arrow slot first, with the thicker side facing down. For the best shooting precision, use the bottom slot as shown in the picture.
    

   

   

2. Tilt the fin and slide it all the way into the slot. Using pliers is strongly recommended.

   

   

3. Put the other end of the fin into the slot.

   

    

4. Glue the fin all around

   

5. Repeat the gluing process two more times and let the glue dry.
    

   

That's it! This is your fully printed arrow.
