Summary

Hello!

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!

Max.

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

Print Settings

Printer Brand:

Prusa

Printer:

Rafts:

No

Supports:

No

Resolution:

0.1 - 0.2

Infill:

10-15%


Notes:

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.

How I Designed This

Fusion360

I designed this in Fusion360, carefully measuring the optimal cell dimensions, how much I wanted them to stick out to remove one-by-one.

Just printed in PLA. A long print, but came out nice. All of the holes seemed a little tight, even after cleaning out the little bit of stringing. I ran a 1/4 in. drill bit quickly in and out of each hole. Now every round drops in and out as smooth as can be. Worked the lid back and forth a dozen times and it slides like butter now. Gonna have to make another. Thanks for your work.

Thank you for the feedback! Glad to see that it worked for you. And yes, depending on how I've sliced it and my print settings, I've had mixed success with the holes being neat right out of the print, I experimented with the setting for the nozzle to avoid crossing open spaces, but that slowed down my print by like an hour and even though it was better, it was still not perfect, the best I've ended up using is to use some of my round wire brushes that I use to clean my barrels, and that works amazingly well :) - Upload some pics when you can!

Wow great visual design!

Just what I'm looking for, but in a 6 round design (some matches require it). Another thing for the wishlist ;P

Hello! Thanks! - You mean 6 rounds in each row? And 120 rounds total?

I guess no design will fit everyone's needs (unless its fully openscada =) but the competitions I'm thinking of consist of shooting 6-10 matches of 6 rounds each, so 6x10 would be a perfect fit without excess weight to carry around. These matches are very popular in Scandinavia where you shoot stationary/moving targets in various terrain.

Hello again :)

I am going to post an [I Made One] this week, but I was wondering... did you have any trouble with one of the holes? I printed one the other night and every round fit perfectly except for the second to last row (on the right) on the bottom, looking at the case as you have it shown in the photos. I had to wallow that hole out quite a bit to even get the round to fit at all, albeit a little too snug to just fall out. I figured it was just a glitch of my print, but I printed a second set yesterday and that exact same hole had the exact same issue. No big deal, I was just wondering if it was just me?

Hello, Thanks for the feedback. No, I've printed this box in PLA 5x and TPU 1x. The 'tight holes' issue that I have is random, and it's usually just a bit of stringing. After reading your comment, I went and checked my model and my sliced model for any irregularities, but I couldn't find anything overlapping there.
You might want to check your slicer, it might be starting/ending a layer in that hole always at the same point, which might cause a rather large blob of filament to collect there. All the 'adjusting' I've had to do was 1-2 holes per box that had a bit of extra stringing.

Great design! Tight fit at the beginnig, but after some "play time" it firts perfect and works great.
Can You please design one for 9X19mm for 50 or maybe even 100 rounds?

Hello! Thank you for the feedback! - Yes! I'm working on a 9mm box!

It'd be great if you could post a pic of your print and share your experience, did you print in PLA?

Just wanted to see if there is any update on the 9mm version?

Thanks!

I tried to modify this one to make the 9mm, but it turned out to be more trouble than I thought so I started from scratch, I'll see if I have enough time this weekend to finish it :) - but thanks for checking in!

This design is super slick! Planning on doing any for other calibers? 9mm would be sweet ! :)

Thank you! I appreciate it! I did a .22 WMR for someone that asked, but I haven't uploaded it yet. I'll be working on the 9mm next!

I appreciate your design skills. Going to make this soon as a gift!

Thank you! I hope it works out!

Good stuff, I like the beehive feel to it with the yellow and hexagons.

Thank you! Kudos to you for the great idea for the form factor! :)

Now where were you at a week ago when I was looking for this?

:)

Probably thinking about designing this! - Make one and let me know if it works out! :D

lol... I designed my own - https://www.thingiverse.com/thing:2831038 - since you weren't around, but I may print this anyway. It is much cooler looking than mine :)

.22 Caliber Long Rifle Ammo Case

Thanks! I Saw yours and I really liked it as well! - I think it'd be great if you'd make a notch on the lid and the rails to keep it in place :)

plinking at the range just got a little bit cooler thanks

Haha! Thanks! Let me know if it works out for you! :D
