I somewhat hoping for a remix of "customizable alternating orientation" but to this day there are none.

I finally got the motivation to do such remix where there's an option to do alternating orientation to have a serial battery setup and also keeping the old orientation for Parallel setups.

Credits to

• enif for the initial customizable battery holder.
• nhorvath for the alternating calculations

As you may have noticed, there are multiple entries of each battery size for example "18650" vs "18650 Standard". Those without "Standard" postfix are the ones by the original dimensions in this openscad script by enif, while those with "Standard" are the dimensions referenced from Electrodoc or Wikipedia

Tick "Alternating" if you want to use Serial setup, untick for Parallel setup

Bottom wire channels and has been adjusted to be matching to each other when in alternating mode

Changes are made to include at least OpenSCAD version 2019.05 that has json file for parameter presets.

Holes for wire inside are bugged right now on different battery sizes, I'm unsure how to make them perfectly matched each other, modifier as follows
for(x=[3,l-7])translate([x,-d/2-w-ws-1,w])cube([3,w+ws+3,2]);
