Thank you for taking a look at my 'thing'.
I looked around for an ammo box for .22LR rounds, and even though there are great designs out there, I couldn't find one that I was truly happy with. One of the best designs I was able to find was one from EvolvingExtrusions (https://www.thingiverse.com/thing:2265904) - I really liked the general idea and the looks, but I wanted to pack it in a box as small as possible.
I also wanted a system that would allow me to easily draw 10rds at a time. Something that'd lock, easily stack, and lightweight.
So I gave it a shot with Fusion 360 - I really like the hex approach. I measured everything carefully to find the best compromise between sturdiness, usability and size. After 9 other prototypes I landed with this design.
I hope you like it, and I'd love to hear your thoughts in the comments - particularly improvement ideas!
PS: Yes, the gun in the pic is not a .22 :D - It's a HK VP9 - I felt too lazy to go grab the .22 :D 2
PSS: 9mm Version here:
I always focus on ease of print for my designs. You should need no supports or rafts, and I found that a 0.15 layer height was a good compromise between speed and quality.
I printed this in PLA and the fit is perfect. If you are using PETG or ABS, you might have to scale up 1-3% depending on your filament.
I did have a TINY bit of stringing inside the hexagons, so I had to 'clear' it by gently jamming a screwdriver in them and even them out :P
Also, the lid is designed to be tight, if you play for it for a while and let it break itself in, you'll find that it slide nice and smooth without losing it's snap. I Also printed a lid in flexible filament and it worked well.
If I get good feedback on this, I'll design a 9mm version of it as well.
I designed this in Fusion360, carefully measuring the optimal cell dimensions, how much I wanted them to stick out to remove one-by-one.
