About this 3D model

Updated @ Jan, 22nd, 2024 I've noticed some feedback that my default profile does not perform well on A1 series, mainly because of the overhang of the barrel and main body. As I don't have a A1/A1 mini printer to verify, please be cautious if you would like to challenge on A1/A1 mini. And I would appreciate if anyone could share his/her A1 profile if succeeded. ----------------- Story continued from https://makerworld.com/zh/models/39368#profileId-38480 Once the kids know what their dad is capable, their dad got mind blown. So this time, I started from scratch and made them happy again. This model works as the thumbnail GIF demonstrated. The total range is around 7~8m, effective range is around 3~4m, should not worry about breaking your window, but I won't recommend to try it. The assembly manual is in the thumbnails, should not be hard for you as you have already own a printer. As I am not a glue fan, this time I adjusted the fitting relatively tight, especially when installing the “hand support”. My suggestion is applying some lubricant and use a small hammer gently. ---------------------- There are 3 parts need to be prepared separately bow string: the rubber diameter no more than 2 mm should be OK. I bought from here rubber ring: I used the same rubber ring with my katana, the folding diameter is 60mm PTFE tube: you could cut from your AMS. I did that. ---------------------- I am not a aerodynamics expert. Although I tried several approaches, I could not find a better bullet shape rather than ball shape. I really hope anyone would like to help to design a good bullet shape.
