Every Day Carry Battery Case

Every Day Carry Battery Case

This battery case allows you to carry up to 4 AAA or AA batteries while keeping them protected from impact and accidental shorts. With the included mount and clear markings, you can swipe a set of batteries at a moment's notice.

Each case has a snap-fit lid with clearly marked battery type on both the bottom and the lid of the case.

When you're not carrying your spare batteries, you can use the included mount to store them. Included on each end of the case with the battery type is a recessed circle for adding paint, stickers etc to help you organise your battery cases. My original use case was to have a Green marker showing for fresh batteries, and Red for fully discharged batteries. See the photos for this in action.

The mount can be used in most orientations, but was designed to mount below a shelf or work surface.

Update 29 July 2022

I have increased the clearance on the clips for the lids for the AA and AAA cases. V1 had a very slight bow which left a visible gap in some cases. The V1.1 lids should look better. There needs to be some friction for the lids to stay on, so there will always be a small amount of deflection in the lid.

The V1.1 lids are fully compatible with the V1 cases, so you don't need to reprint everything - just the lids. 

I have also uploaded individual STL files and STEP files for easy modification/remixing.

Print Settings

Cases

The cases should be printed with either the AA/AAA text or opening on the build plate. You can print it with the back of the case on the build plate (curved front facing up).

Lids

The lids should be printed text down on the build plate. The clips may benefit from a smaller layer height, but I personally haven't had any issues with a chunky 0.3mm layers (via 0.6 mm nozzle).

Mount

This is probably best printed with the screw holes on the print bed. The files include a 2 slot and 4 slot mount. If you require more slots, you can simply attach multiple mounts to your shelf/intended location. Alternatively, you can position two mounts together in your slicer and they should be printed as a single model.

For all parts, layer size, perimeters, and other settings are totally up to you. Infill shouldn't be needed.

Material

Again, this is totally up to you. I have used various PLA filaments for mine and have had no problems. The colour of the filament is an opportunity to colour-code your cases based on the chemistry of battery (Ni-MH, LiPo, Alkaline, etc) or whether they're rechargeable or not.
