Anyone print gun stocks? I have a weird custom build 300 blackout on a Rem700 action and the MDT stock I have is way too heavy and technical, this is meant to be a plinker...

So I was thinking of printing something that would use a AR rear stock, and work with my 10.5" heavy 300 BO barrel...

I could start from scratch using the MDT stock I have as a model, but hoping someone has done something similar.

Thanks!
 
Never heard of 3d printing a stock - always assumed 3d printing wasn't up to the task considering the forces applied during firing and rough use - but I'm interested to see where this thread goes.

300BO ain't no elephant gun. If anyone wanted to try what the OP is contemplating it would be a decent candidate.
 
PETG-CF and PA6-CF with annealing are 100% up to the strength and heat specs, hell PLA-CF would probably be fine too. The problem is see with making a stock is print volume. Usually capped at 10" unless you have access to really expensive industrial printers.

10.5" barrel and using a AR rear stock, so the stock should fit, hopefully...

And I like the idea of subsonic ammo, so very little recoil.

I have a Bambu A1 but my buddy has one that does CF, so i could trial and error on mine and get my buddy to print it

I may mess around with a design in OnShape
 
Not into 3D printing but I am curious how far it can and will go. My first thought was will it handle the stress. Second how big of a printer is needed. The idea behind it I like. Making just about any object you can dream up. From what I have been reading it just keeps improving. Strength is the limitation that I see.

Modern materials printed at high temps are approaching metal. Check out the specs on the CF-nylon at Pantheon design. I have one of their printers and it's stronger than a lot of aluminum alloys for weight on bending and approaching on pure tensile strength. You could absolutely make a stock out of it.

The biggest problem with 3D printing large objects is the length of time required to print the part.

That is much less of a problem with the current batch of printers. It still takes time, but they are much faster and more reliable than previous generations of machines.

My concern with OP's stock is where the AR buffer tube threads into the printed stock body. That is always a problem area. If he follows the design concepts of some recent printed AR lowers it will probably be OK, but that is always going to be a problem spot.

Picatinny butt stock attachments are better suited to 3d printing than threaded buffer tubes, adapters are available if you want to reuse some parts bin stuff

oooh, look what I found

https://www.stlfinder.com/model/remington-700-rifle-chassis-mMt4XAcY/368721/
https://grabcad.com/library/remington-700-rifle-chassis-1

AND is imported perfectly into onshape!!! Gonna shop off the forend and try a quick print with PLA with low infill just to see what happens

From grabcad: "model is tainted due to a violation of community guidelines"

it might be a good starting place but check out https://www.thingiverse.com/thing:7036947/files for something that wasn't abandoned 5+ years ago.

So this person put ALOT of work into this! 30 page PDF with detailed instructions and all the fasteners and taps you need. Printing a draft now just to see.

Here's the main stock imported into onshape

This was on super low quality "draft" setting with only 15% infill with PLA that's been sitting out for months (may have been a bit humid) and it turned out great! OAL length is about 30". The thing is solid! IMG_2109.png
 
Still need a bit of hardware, but it's coming together! Y'all think anyone is interested in buying some of these? I'm thinking about ordering hardware but it only comes in bulk... I'll also be adding a front swivel sling stud for a sling / bipod...IMG_2119.png

That's looking pretty good, did you remix the front to remove the hand guard attachment spot?
I never did download the file pack, what kind of hardware does the build sheet call out?
The design looks like it uses a trapped castle nut for stock mounting, I would want to swap/remix that to picatinny for my purposes.
I'm mostly waiting for you to beta test the magazine system for me :LOL:
 
Really cool thread.
We run industrial 3d printers at my place of work.
I really like where you are going with this.
