    Yep. There's a 33 rounder too that takes Glock 18 springs. My friends printer isn't big enough for it though, so I'm trying a small one first.

    Sure a 33 round Suomi Mag would be nearly free, take standard springs, and work in Lage uppers but would your efforts be better spent on a more practical 3d print like this:Name:  best 3d print.jpg

    It's in the same zip as all the rest. They have some caveats as to it's effectiveness so not an endorsement on my part as I haven't even shot the small one yet. I hope this gun actually works with Swedish stick mags as well.

    Thanks! Didn't realize that was in there. I have the zip but have not been able to open it and start printing yet.


    What is the Sumac tile puzzle in the zip?

    It's just a little slider puzzle you can print that has an image of the SuMac on it.

    Thanks! Ill try it out for giggles.


    Printed one of the small mags yesterday. Seems to fit the Lage Max10/31 mostly. Feed lips are a little wide and need to be clearances and I think its touching at the back of the feed lips making removal difficult but otherwise should work. Wilson has some springs for the G17 available for $1.60 a pop so I may have ordered quite a few. I can print quite a few of these and throw them away every 10 loads and still be out ahead vs a shockwave mag or a coffin at this point.

    Deerhurst, I had figured I'd just borrow a glock 17 spring and see if those work. Also, if they prove useful minus feed lip wear, I wonder if we could use Lage's feed lips? Did you print a PETG follower? notes say:

    A PETG follower may help.

    The mag password is.in the readme txt file.

    I ordered a few springs. I can always use spare.mag springs. I'll probably print a few Glock mags anyways. I'm tempted to print a Glock frame and machine the rails for maximum middle finger to the AFT!


    I printed the follower in PLA+ and touched it up with some 320 grit. Slides like a dream with 10 seconds of work.

    The feed lips need a tiny re-profile for my Max10/31 bit not a.biggie. Cheap enough to print they are basically disposable. Save the spring and keep going!

    I didn't catch the PETG tip. I'll run a couple as is and see what happens. Might even do a little anneal on the bodies. Should make them tougher.

    Is that a MPA or Velocity upper?
    Did you ever find out if the uppers are the same dimensions?

    Vmac9. I just got it all together last night and should have measured first, but I will at some point.

    No it will not fit. No you could not make it fit.

    You could make your own version for it perhaps.

    We just published a video about our using PS/31 Zmag Adapter (it works beautifully!) and OEM Uppers with the Poison Sumac (they work just fine but the bottom rear of the sheet metal must be relieved to allow for the hammer to function):

    Enjoy!

    Good job. Is the PS semi uppers the same dimensions as the Vmac9 uppers?

    Anyone tested the printed lowers for longevity? The Sumac does not appear to have a lot of material connecting the front to the rear.

    The Vmac uppers are slightly larger all the way around. We have very few rounds in our poison sumac lower. We only printed it to prove that our parts would work.

    I can tell you this design is not for serious use. You can't remove the upper without completely disassembling it for starters. It should also be a single solid piece instead of all these pieces put together with a threaded rod.
