Center Fire Ammo Boxes - Revamped design

thingiverse

I designed a series of ammo boxes a few years ago that were based on a design I saw here on Thingiverse. Over the years I've received multiple requests for boxes in calibers that I don't own. Because of how I designed those original boxes, it was very time consuming to add additional calibers. You can find those original boxes here: https://www.thingiverse.com/thing:1559655 This is a new box based on a revamp of my old design. I've made two significant changes: 1) The box design is now parameterized so I can change/add new round types very easily. It only takes me about 5 minutes. So if you want a new caliber that I don't have yet feel free to ask. 2) I redesigned the hinge to be a more industrial type hinge. On the old design it used a nail as the hinge pivot. This new hinge uses a M2x30 Box Head screw. The holes on the hinge are threaded so be sure to NOT PUT SUPPORT in the hinge holes. You won't be able to get it out and won't be able to screw in the screws. See printing instructions. 3) My old boxes were designed to all have the exact same external dimensions. That was a decision I made when I was reloading similar sized pistol calibers. But as I added larger rifle rounds to my mix I needed to remove the size restrictions. These new boxes change their external footprint based on the caliber specs. So a .38 box will be smaller than a .45acp box. The common factor is they all hold 50 rounds. I now can print any caliber I want. Items needed for assembly: M2x30 or M2x25 for hinge assembly. https://www.amazon.com/gp/product/B07PXZ4FTL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Printing: Print using what ever material you want. I use PLA because PETG is too slow for me. I use Cura as my slicer. My instructions are based on that. Bottom: Print with NO SUPPORT Top: Print with support everywhere EXCLUDE support from the hinges. If you can't do that then print with NO SUPPORT. Assembly: How tight these fit together will depend on your printer tolerances. My printer holds excellent tolerances so it prints perfectly for me. 1) Place the top on the bottom. Fit will be tight!. Don't worry, it will loosen up over time. If you printer has sloppy tolerances then you may have to file here and there. Make sure its completely closed and the latch is pushed in tight. If the latch is tight a quick file on the lip will lessen it up. Screw in the hinge screws. Exercise the box a dozen times or so until the latch latches smoothly and the hinges open and close with the desired pressure. The box 'wears in' then works perfectly. Side Note: I will be posting several calibers over the next few weeks. As I add calibers I will note whether or not I've actually printed them or not. 99% of the time these new boxes print fine first try. If for some reason you print a box I haven't printed and it needs adjustments please message me with which dimension needs attention and I'll post a fix. Have fun.
