ANVIL Magazine Full Length Mega XL Mod

This remix of Silly's ANVIL mag fits full-length Mega XL Nerf darts with no new hardware, AND fits normal shells too! It has that cut at the top so magwells like my ANVIL Full Length Mega XL Mod can still fit normal mags too! I've included those parts in the step in case you want to design around this important backwards compatibility feature!

I also added many internal ribs to help reinforce the feed lips now that they're further from the mag walls.

For blasters with feed ramps, a more significant blaster redesign is likely required, as the feed lips have to be so big and forward to work in ANVIL and be strong. The optional TPU MagBumper has been extended but won't fit in magwells on the 2 or 3 shell versions, so I excluded their screw holes. I also moved the numbers up to not get covered.

I suggest aligned seams (Avoid the follower slots) 5 walls 20% Cubic infill. The step/stl files are NOT ORIENTED FOR PRINTING and please make sure you use NO SUPPORTS (they make spring assembly impossible), please use the 3mf or check the image below:

You'll need a blaster for this, and right now the only option is the ANVIL, but please note that I separated these because the mags should be universal, and supports are different between the mags and the blaster. This magazine need to NOT have supports in the spring slots.

If you want to try 9-round shells, please note that you will likely need higher spring loads to fire them all and only 107mm triangular shells will eject reliably, I use these:

But they also tend to have massive spread and bounce in the barrel.

I'm already working on a double stack mag, much longer mags (both for big printers and bolted together), MOLLE/P-LOK magazine holders, and an elastic version of these mags. Please dm me on discord @vestedclover if you'd be interesting in beta testing or have any issues or requests!
