As with any of my designs born out of immediate necessity, I ordered a battery pack online... only to realize I had selected the wrong size. But fear not, here comes the solution.
A battery box designed for a single AA battery, capable of being combined in sets. Both alignments are possible: parallel (with all positive terminals on one side) or serial (with positive terminals alternating). No springs are needed; it utilizes PLA resilience to maintain good contact, requiring only a wire as depicted in the attached images.
When inserting battery: put PLUS side first.
Caution: Due to the specificity of each printing environment, sliding elements may require some adjustment. For my Prusa MINI, there is a 0.3mm size difference between parts (as reflected in the included files).
I have tested this design with batteries from three different manufacturers, as well as one rechargeable battery from Apple. In certain instances, a slightly larger plus side hole may be necessary. However, I maintain the design in its current state to ensure a snug fit for improved grip.
The PLA used for the pictured elements is PRUSA Translucent.
I've also made a variant of this design for AAA batteries.
