Hi - I saw your Mopeka tank check holder that you 3D printed and was wondering if you could help me with some dimensions. I am trying to 3D print a holder for the Mopeka to use on the bottom of aluminum cylinders, but my trailer (with tank checks and cylinders) is 1500 miles away from my home. Any chance you could provide me detailed measurements of the Mopeka unit, or a 3D file (I use Fusion360). I'd really appreciate it and happy to return the favor if there is something I can do to help you!
