So I was looking for a case for an AZ-Delivery CP2102 USB to TTL Converter (https://www.amazon.de/gp/product/B07N2YLH26/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1) and found this model on Thingiverse: https://www.thingiverse.com/thing:1986046
It was a little bit too short to fit Dupont Connectors, so I made it longer. I use the converter to power an ESP-01S (doesn't have a USB port) from an old 5V USB phone charger.
The author remixed this model.
