Description

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.

Not gonna lie, wish the barrel was just a hair bigger to accommodate about 25mm. This would accommodate most Nerf darts except the XL 30mm ones. Any chance I can get the CAD file to see if its possible to remix it slightly bigger?

Second that! Having a NERF crossbow would be awesome!

@niltsh

Thank you for the hint. Actually I am going to buy one set of nerf darts.

Replying to @niltsh :

I spent a lot of time scaling it in the slicer 140% in only X and Y, some parts only in Z. The bow front parts I had to split and JB weld together. Finishing tonight and I'll post my make. But yes, simply enlarging the barrel would solve this lol.

@azretracr

Has anyone successfully printed this on the A1? My son has attempted this twice now, and is having overhang issues on both the main body parts and the barrelup pieces. unfortunately this has caused problems with them fitting together. We’re going to try sanding the roughness out a bit and see if we can make that work. If not then we’ll probably reprint on my P1S.

Same issue with the top rail on my A1, its the overhangs. Too steep for the cooling on A1. You can lower the layers to 0.12 or use the P1S

@azretracr

Replying to @TheMidnightSmit :

ugh. looks like it’s doing it again. the other two appear to be okay so far. I’ve skipped this one and will try again.

@niltsh

Sorry i dont have a A1 in hand. I only tested it on my X1C
