Ultimate Modular Battery Holder (AAA, AA, CR2, C/R14 , D/R20, Coin, 9V/6F22, 18650)

This is an expanded version of Jason D Modular Battery Holder. I've made several changes to clean up all the “remixes” out there, make the modules truly standardised and “OCD friendly”. I was basically annoyed how different remixes despite fitting together with original still had wrong dimensions (length, clip position etc.) so i decided to remake everything while keeping them compatible with original design.

The remix consists of modules to hold most common battery types such as: AA, AAA, C/R14, D/R20, CR2, CR2032, 18650/18XXX, 6F22. For AA and AAA batteries there are two variations, slim that fits 6/7 batteries and wider to fit 8 batteries (as they are mostly sold in sets of 2/4). It also comes with utility modules (see at the bottom). All modules:

• have exactly same dimensions and rounding on inner/outer edges, the only difference is in their width and shape of battery holes
• removed labels as you won't see them anyway with batteries in your drawer
• reduced depth of some battery holes so that at least half of battery will stick out (easier to grab)
• fixed dimensions of holes with appropriate tolerances so that batteries fit nicely but they are still loose enough so that pulling one out does not lift up whole module, dimensions taken from manufacturer documentations/standards and checked against off-shelf batteries with some exceptions
  • for 9V/6F22 as it seems that manufactures don't care about the IEC 6F22 standard and make their batteries of different smaller size, for that i created one module variant that has exact dimensions of 6F22 battery and it will appropriate for all undersized 9V batteries (<>tight.stl) and one that has extra margin so it should fit 9V batters that are actually of correct size
  • for USB module as above, manufacturers have their dimensions all over place so its made to fit worst case scenario (USB connectors that are maximally oversized)

Utility modules are universal trays in two sizes, blister tray for coin batteries in packaging, USB tray for pendrives and dongles. Additionally I'm attaching some dummy plugs/modules so you can close up a section of modules with a “cap” and blank module in case you want a bit more of spacing in between your modules.

All prints without supports. For Starter/Ender pieces you might need to enable brim for improved bed adhesion.

If you need a module for a specific battery size write in comments and I might add it to collection.
