14500 Li-Ion charger (TP4056 based)

I needed a simple and easy to carry 14500 Li-Ion charger and did not find a convenient model on Thingiverse, so I designed one.

You'll need a TP4056/USB charger module (easy to find on Aliexpress or eBay for a few cents), preferably without "battery protection" circuitry as this is only a charger: See the included image as a module example.
You can use (salvaged) battery contacts as I did or use nickel strips. Again, the dimensions of the contacts you'll use can be adjusted in the source fil
