I made a charging dock for my precision screwdriver. The brand is King'sdun, I got it from Amazon Japan, but I have seen unbranded or different brands being sold around the world that seem to use the same design, this is the one I used for the design https://www.amazon.co.jp/gp/product/B08TBRSWVB/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&th=1). As long as it's round, 16mm thickness it should work.

To be able to easily dock it after use I decided to get a magnetic USB-C adapter ( https://www.amazon.co.jp/gp/product/B0CPPNZ4DN/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&th=1 ). I did a quick search but couldn't find a standard for those, so the one I used uses round magnetic connectors, 9mm diameter. I included the STEP file in case you need to tweak the size to fit the connector you're able to source. The cable must be able to rotate the connector or be a L shape type.

The cable goes in the base and it's locked in place by the dock, which is secured by 4 M3x10 screws. I also designed a cap for the screwdriver end because I thought it didn't look great having just the USB-C to magnetic adapter.

The magnetic charger is stronger than the 4 standard Gridfinity neodymium magnets together, so when you try to pull the screwdriver it just brings the whole dock together, so I recommend screwing it to the baseplate.
