.223 AR15/M4 mag 15 rnd Speedloader

UPDATE 5/17/20: I've completed updates 2, 3, and 4 that I thought would be good. If someone could please try it and let me know how it works with the bottom ribs, I'd be forever in your debt. I've printed several of the speedloaders on Thingiverse, one of them being https://www.thingiverse.com/thing:2528734 by Pyro Scooter, which is the great-granddaddy of the one you see here. It morphed some under https://www.thingiverse.com/thing:2805177 .223 30rd Speedloader, AR15 by Dave Root and further with one by Seathru at https://www.thingiverse.com/thing:3873861 that I printed. However, I didn't like how thick it was, and I didn't have a spare mag release to use. So, I modified some myself, combining each of these models: https://www.thingiverse.com/thing:2805177 .223 30rd Speedloader, AR15 https://www.thingiverse.com/thing:4280455 Stanag Magwell Profile https://www.thingiverse.com/thing:3320337 AR 15 M4 Holder Magazine Holster V2 I came up with what you see here: * One with a profile bottom and one with a flat bottom * With a mag catch integrated I thinned the top height on the sidewalls, tested the catch several times at different positions, and it drops right in and locks with my Gen 3 20 rnd PMags. I'll be printing one for a friend who has 5, 10, 15, 25, and 30 mags, both metal and plastic, to see if it works with all of them. At .2 resolution, it should print in 6-8 hours roughly. Based on Seathru's suggestion, I printed this on its end, trimming the magwell down so that the tips of the retainer are touching. It doesn't really need a full-depth magwell. Printing in this orientation also limited the amount of support. Printing it flat makes the support inside the mag nearly impossible to remove. Be sure to put a finger on the retainer since it's only PLA, and you might see the mag and rounds go skittering across the floor if you don't. If I had a full magwell model instead of using someone else's, I would align it better with the tray as it is just a little far forward of being lined up. It does load but the rounds are loaded 1-2mm forward of the back of the mag, so be sure to bang them on the back edge to align the rounds. My skills are pretty limited, and I use Tinkercad. If you'd like to have a hack at the models in that environment, here they are: Flat Bottom: https://www.tinkercad.com/things/6vKPp1L4Icv Profile: https://www.tinkercad.com/things/1d7Otgcasnu Suggestions for future mods if anyone wants to take them on before I get around to it: 1. Line the magwell up better. 2. Trim the magwell down a little so it's not hanging in the air if you print it on end. 3. The holes are annoying, and the rounds sometimes end up falling through, so fill them back in. 4. Maybe some little indents where the rounds lay to keep them from rolling one way or the other. 5. As I look at it now, perfect to go into my range ammo box, I wish the pusher was captive and maybe a little narrower so that once I put it in, it was retained, but that will take some thinking to get right. 6. Of course, there are going to be those who want to make it a full 30 long. Get on down with yourselves; I only use this at the range for quick reloads, and my mags are 20s, so two quick rips, and I'm full.
