Gridfinity Portable Solder Station

Inspired from having to travel with my soldering iron, I decided I needed to make my stuff more portable. I printed most of these in 0.28mm layers (with exception to the fume extractor box.

All materials fit in a 5x4x6u box (I used the one from Pred). 

The major hurdle for this was building a mini fume extractor that would fit in a 2x2 but maximize airflow. I found that an 80x80x25 would leave enough for a filter in a 6u but would be insanely tight. Instead of carrying around a 12v wall wart or some other supply, I opted for a slim USB-C trigger board that can do Power Delivery at 12v. Details here. Components and files for this located here:

===EDIT 4-30-2026===

I added the tip tinner lid. Unfortunately the original lid was too wide for a single gridfinity box so I had to design a separate lid. I don't really like this design, so I highly encourage a separate solution. I ended up having to add a layer of capton tape around the perimeter to make it a snug fit.
