USB-powered soldering irons have become very popular recently and sell on Ebay for less than £5 (http://www.ebay.com/sch/i.html?_from=R40&_nkw=usb+soldering+iron&_sacat=0). Their power rating is low (<5W) but their ridiculously low price make them very appealing as portable soldering tools for small components. I thought I'd make a 3D-printed support to hold two of these irons together so I could use them as soldering tweezers.
The files I post here correspond to the second iteration of the design. It is far from perfect but it works!
It needs support material and prints in about 45 minutes using light infill and fast print settings in an Ultimaker 2+ extended with PLA and a 0.4 mm nozzle. I suggest printing this laying on its side. This way the printing layers are not perpendicular to the beams that connect the two sides, which makes them easy to break when they bend.
