Rubbermaid 2.5 Gallon Gas Can Cap

thingiverse

This will fit Rubbermaid 2.5 gallon gas can with a 4.25 mm thread pitch. This will NOT fit Midwest or Blitz cans with coarse or fine threads. Three models are included, one closed lid, one lid with a 31 mm spout hole, and a spacer that is sized to fit a standard gas can spout gasket (1.45 mm od) and set into the gas can mouth. The v2 version has adjusted the threads to not cut as far into the top as the original.
