I decided to combine a solder fume extractor with attachable helping hands. I have two slots for mini rocker switches since I also included a custom LED light. I am powering this with a 12v 5amp DC power supply. Designed this around a 120mm x 38mm fan, but will work on making a 25mm revision. I made the top and back cover assemble with neodymium magnets to make sure they lock into place.

The arms for the coolant pipes (helping hands) are separate components and snap into place - I made it this way so it can be used without them if you don't like them or want to save some space.

I printed without any supports, but I recommend supports for the back cover to make sure everything looks good.

I will make a cap for the rocker switches in case people prefer to only have one.

I suggest supports for the rear door only.
