So I had asked a while back if anyone had a 3D model of the Tavor:  https://bullpupforum.com/index.php?topic=11094.0
I ended up paying a bunch to have the gun scanned.  Let me know if you would like the file to use, but know that the dude paid most attention on the grip so the other areas might not be as great fidelity.

Here's what I came up with after many hours and iterations and one pissed off wife Cheesy  It's not quite done as the tabs don't snap solidly in yet, but I gotta lay low for a bit with the 3D modelling lol.
Let me know what you think!

That is cool. So they scan the original with lasers I am assuming then convert it to a 3d printer file?

That looks great. I thought this was going to be a kydex wrap riveted together.

Looks like one of those sci-fi movie rifles now.

I think some of them use lasers, but the place I scanned it used a machine that used white light.  I think it was an Arctec Eva.

CA defines an assault rifle as having one or more of: flash hider, forward pistol grip, rear pistol grip, adjustable stock.  So this thing prevents the rear pistol grip hold lol

Thanks for the compliments guys!

So according to Cali law, adding a VFG to ANY rifle makes it a Assault Weapon?

If it's a flash hider, then yeah, you now have an assault rifle.

What is that safety selector? Is that to satisfy another CA law?

Nah no funny laws for the safeties.  I just thought I'd make a thumb rest safety so that it's more comfortable to hold with the fin grip.  You can see it in the pic.  I did make 2 other safeties as well.  You can see one of the on the left side of the gun in the pics.  It was ordered as red, showed up as an orange red, but photographed as yellowish lol.

I've attached the other one.  It's also designed for the funny grip, but I guess it could be used on normal non-retarded CA guns too.

So because you can't wrap your thumb around it it's compliant? Clearly that makes the rifle far less dangerous  Roll Eyes. Lol

Yeah, I think it's fear of the aggressive look of a pistol grip, so they defined it as being able to place the web between the thumb and index finger below the top of the trigger while in firing position.  It's really just funny logic and definitions.

I used a caliper to take my measurements, but they're still not quite right. I used a 3d program to create the model and then sent it to shapeways.com to print it out. Gotta fiddle with the model a bit more and then print it out to test the fit again.

Well, I happen to have a 3D printer and a X95!!!  Grin If your looking for a guinea pig!

I've printed the safeties on an FDM printer and the layers don't fuse well enough and the safety ends up breaking, and the locking tabs on the fin crack or break off.  I'll post the safeties and the fin up soon on Shapeways once I get the fit a little better.  I've made a bunch of iterations but it's still not quite right.

I'm from there. It's looks nice but it is bs we have to do this.
It's like a game with these politicians and see how far they can go and see us keep trying to comply with these rules
