I stumbled across a video from Shop Therapy called "Design And Build Your Own Power Bank" and was inspired to make my own version of a Power Bank using an empty Respawn Mint Tin.

It turned out that 2 18650 power cells fit perfectly into the mint tin body. I then created a 3D printed cap/head that holds the USB-C PCB board and snugly snapped into the top of the tin.

I then created a cap to hold the USB-C board and after many iterations, I ended up with my final fully functional power bank!

I also added fuzzy skin on the final design in Prusa Slicer to hide the random seam placement & give a little more grip.

Respawn Mint - USB-C Power Bank - Cap

————————
Materials List (BOM)

Item	Price	Note
18650 Battery Packs (x2)	$27	I didn't want to mess with soldering lithium ion batteries, so I purchased pre-made versions for safety & easy assymbly
USB-C Power Module (x4)	$12	I selected this because it was only ~19mm tall so the 3D printed cap could be as short as possible.
JST-PH 2.0 Connector Cables (x10)	$8	Using this cable allowed me to easily connect and disconnect the battery from the USB-C power module. The only soldering I had to do was the male cable to the power module.
Empty Respawn Mint Tin	$3
Total Cost	$50
