Modular Outer barrel system M14x1LH airsoft

I made a superior outer barrel system, easy printing and stronger?!!

Hi!

Since printing threads and outer barrels sucked, I came up with a system that is both superior in strength and printability.

Printability: hexagon o nthe outside, triangle on the inside. PRINTED FLAT, and only needs supports on the ends.

Strength: the main issue with using printed threads is layer separation. To prevent this, a possible solution is allowing local deformation of the material!
How can we do that?

Outer thread: there are 3 threaded sections and 2 blank ones, it is also slanted on 3 sides and the profile is modified.

Inner thread:
I added 6 assymetrically chamfered lugs, and modified the thread.

(It is fully compatible with standard M14x1LH!)

Features:

-goes almost right into slot, no fiddling anymore!

-Very hard to overthread, and even if it is, it will hold

-Not even slight layer cracking under my tests

-Can be printed from PLA too

Printing settings:

0.15mm layer height
-Tree supports,on buildplate only, and critical regions only.
(Or hand-paint it according to the pictures shown)
-10+ walls
-It is fine to print from PLA.

UPDATE 2025.12.10.:
I can't fight tolerance variables between printers-materials-settings-environments-etc, so I came up with a solution:
There are now version with added clearance in the female threads. They are marked "+0.05" for example in the file name. Make sure to do a test print before if you care about material!
This is the best I could do after days of trying and trying.

CAD files also added, feel free to remix, but share same way and tag me!
