This is a remix of the Heat Gun Holster by ModaModular on Thingiverse. It has been adapted to fit on a 2 piece pipe clamp style ring that fastens together with M3 screws to mount on a vertical pipe, pillar, or tube shaped support. The inner diameter is 100mm, however this can be successfully scaled up or down a few % without affecting functionality negatively. The Harbor Freight heat gun fits great.
