I've printed a dozen or so of @jed_183683's powerbanks because I have an endless supply of salvaged 18650s. He already has a 3-cell model, but I needed a flat one for my application, so I just took his 1-cell powerbank and stretched it out to fit 3 cells.
Advantages: only need to cut 1 nickel strip per side, no need for internal cell holders of a specific shape
Disadvantages: less structurally strong, lots of dead space on the top, requires a bit more filament and printing time than his 3-cell powerbank.
Uses a 5v boost module, I get them in bulk cheaply from AliExpress as well.
Also drew a simple wall mount for this, I made it to power a string of LEDs and needed a convenient place to put it.
