This is 3D model for TS100 digital mini soldering iron, which can be used to design TS100 accessories (boxes, stands, holders, etc.). Model include Fusion 360 project, as well as STL files for: TS100 body, TS100 tip, TS100 with tip.
I believe that model has 0.1mm accuracy or better. You should probably use about 0.15mm-0.2mm clearance for 3D printing.
