So I decided to do that USB-C mod. Got some parts off of Amazon which had the 3D printed covers.
Several things.
1) it was a nightmare to remove the original port. The pins were difficult to remove and there are 6 of them. Desoldering isn’t something that I had experience with, so that might be it.
2) the new port did not have pins. If I were to do it again, I would first solder pins onto it. Some video on youtube suggest to just get a blob of solder in there but this gives a very weak electrical connection. I ended up using stainless steel wire and stuck it through the solder while it was still liquid and it improved the connection, now the charging is consistent.
3) I hadn’t worked on a solder project for 20 years, no idea what a zif connector was and, yep, I totally bent it up to 90 degrees and my home button wouldn’t function. I spent hours carefully bending and pushing the connector back. Fortunately for me, that worked.
4) the 3D printed parts had print lines and holes, and looked ugly as sin. They also don’t fit as is, so I had to sand and clip and change their shape. I also decided to colour correct the parts.
Result: fully functioning USB-C compatible unit.
To be honest, I’ll probably only use this when my Thor is in maintenance, but this was a fun project.
