This is a magnetic holder for a TS80 soldering iron.
Version 1 - Soldering Iron Holder.stl
This version uses a pair of 10 x 3.5 x 2.25 mm N45 Neodymium magnets in the base of the print to attach it to a suitable surface. I used a tiny bit of superglue to keep the magnets in.
Version 2 - Soldering Iron Holder captive magnets.stl
This version also uses a pair of the same 10 x 3.5 x 2.25 mm N45 Neodymium magnets in the base of the print, this time however they are completely encapsulated by the print, so you will have to pause the print at a layer height of 3.5 mm and install the magnets, then resume the print. The result is that the holder still works well, but it is not held to the surface quite as strongly as the version where the magnets protrude from the back of the print.
