Soldering station with 4 arms and a place to attach a fixture with a magnifying glass as well as rails for additional accessories. Uses M5 screws with a length of 12.5 millimeters but can be converted to M3 or M4 screws as long as the length is maintained. The nuts belong to channels but are used here as regular nuts. The model can be modified to fit regular hex nuts that are in the area.

Print with no supports.  

I printed with 0.2mm layer height in PLA.
