Saw this video on Youtube before I got a printer, decided to make a more compact version.

Wiring design is the same.
I bought the TP4056 & ZB2L3 on Amazon, I am not recommending any specific supplier therefore no links provided. It is important to get the 18650 cell holders with locating nipples on the bottom as they press fit in the base
x2 TP4056 - I did release some magic smoke from 2 of these when I wired the switch wrong.

Printed in PETG at .20mm either 5% or 10% infill will work (your preference).
When placing the holders and TP4056 into place you will have to bend the base a little to allow them to snap in. ZB2L3 reuses the screws from the standoffs.
