Modular soldering helper

I hate soldering various XT and MT connectors and other similar connectors. I wanted something that would work for all the different connectors and wire sizes that I use. So, I designed this modular soldering helper.

The "base" has 3 pieces. The "Solder helper base", the "Solder adapter base" and the "Wire holder". Use whatever plastic you want for the helper and adapter base. The Wire holder is best printed in TPU so that you can squeeze various wire sizes in.

The Plug adapters should also be printed in TPU so that you get a tight fit for your connector, but can still get the connector in and out. The plug adapter has a bit at the bottom to prevent the plug from rotating in the adapter. I've include plugs for mt30, xt30 and xt60 connectors, as well as the "base" plug to make for any other connector you might have.

I've included step and 3mf files for all the bits.  Ignore the multicolor in the picture, I was just using up spools that were almost empty.
