ATI TAC SX2 Pistol Grip

[jr300z]

When I bought the ATI TAC SX2 shotgun back in over 5 years ago, I remember wanting to get a pistol grip for it but nothing was available. I had plans to design one but never got around to it. Now I took the time and designed one and made it with my 3d Printer. Let me know what you all think. It used the ATI pistol grip kit PN: 118-ATI-SPG0100 along with a longer bolt to hold it all together. Pictures show printed in white PLA, im moving forward to print with black ABS or Carbon fiber ABS depending on testing What yall think about it?

First of all, very(!) nicely done OP.

Two questions briefly:

1-What CAD package did you design and print that using?

2-Overall strength? Can you 3D print a resin with the necessary shear/tensile/compressive strength you need in a part like that?

Yes sir, I’m a progressive
Yes sir, I generally, vote Democratic.
In most ways, I’m a San Francisco Liberal

HYPOCRITE! YOU vote for the politicians that want to outlaw those evil pistol grips on black guns....Hell you have even argued in favor of the assault weapons bans.

I used Solidworks for design and I printed using Cura and Robo 3DR1 Plus.

Modeling the strength of a 3D printed parts is often hard due to the nature of 3d printing material. I know from a heat perspective the final version will not be PLA (as pictured) due to warping. Most gun plastics are made using ABS. The main concern with ABS in this application is the impact strength since it will not see tension applications. I plan to do some impact testing using the provided extra adapters that came with the kit as a baseline. If my part survives the same impact then I will deem it good enough.
