Printed my first prototype today, the dimensions are good. The slot for the attachment to the body didn't print well so need to fine tune that. Prototyping in PLA; the finished one will need to be something stronger. Anyone try this or seen a 3d printed one? Ill make this available on thingiverse if it works.

I also made a lens and aperture holder for my Razor Gen 2 scope for indoor training similar to other devices for allowing focal point at about 13 ft. Takes the lens full size at 2.75" so no charge by optometrist to grind to fit. 20$ for a lens and some cheap PLA to print the holder. Ill post it as well, just need to fine tune some dimensions.

Cheers

The only 3d printed mag extensions I've come across are the ones MKM machining makes for the Magpul AICS mags and they're total garbage. That being said, those mags use a totally different floor plate than regular AICS so it's not really apples to apples. I've got a Seekins mag extension for an Accurate mag and I don't see why yours wouldn't work the same. How do you plan on securing it to the lips on the bottom of the mag? The Seekins and Area 419 ones use set screws.

Ill likely use set screw. I just will add a hole to the extension and use the set screw to cut the threads
 
You might want to experiment with the layering direction. By the look of your picture it is printed as you might use it. If so, the layering is weaker in that direction and liable to break with repeated use and the spring force. It might work better if it is printed with the back of extension on the build plate

Thanks for the advice, that was actually printed like it looks, bottom of base on build plate. I have done them the way you suggested also. Just trying different orientations. Prints either way without supports but I was trying to get the groove for the mag attachment cleaner, never thought about the strength, good point. I have one in PETG printing right now.
 
So far so good, holds 12 rounds and prints good. Did a few dimension tweaks and made the back of the extension so the tab on the AICS mag locks it in place with no set screw. Will see how the PETG one works and holds out, the PLA is surprisingly strong when I print the extension on the vertical axis. Anyone want to test one out for me? I'd not run it in a match just yet though.
