Print this with1 wall with a good PLA+ filament and it'll be a strong, fast, and light single-part performer.
Designed for a constant-force spring. Either:
I print mine at 0.28mm layer height,1-wall, 70mmps, and 10% infill. With these settings I can print a full 18-mag in in3h 45m.
Print on a glass bed (with brim for betterstiction) and you can fully automate printing these and one printer can churn out~6/day!
Hook the spring into the top of the mag, pushing the free end into the second slot. Use a ruler to push the spring to the bottom, hooking it over the edge. Put the spring coil inside the pusher you've printed but thenbe very careful releasing it back to the top. The speed it picks up will break the top end clips, so put your finger (or hold a dart) at the top to stop it.
If you do break the arms at the top they're very easily and effectively superglued back. It's the weakest part but stillplenty strong .. for everything but a 50mph plastic pusher smacking it.
I designed this in my cad program of choice: onshape, which means anyone can fork&edit the design. I even added configuration variables for the left & right engraving and dart capacity.. so no cad skillz are needed to generate a custom version. To download an STL or STEP you probably need a free account
Go fourth and rain foam hellfire!
Please post 'em! Really! Take a quick cameraphone photo of your print in all its glory and show it off! Plus it really helps get this design out there to the world.
Designing stuff is fun but interacting with cool people and hearing about their adventures is better. I can generate any variation / engraving easily, message me on discord/telegram and/or leave a comment and let's make your perfect version. I only ask that you post a make!
If you'd like the CAD or STEP file too, no problem. I've already helped a bunch of great folks! Send me a ping
