This is a remix i guess or rather a ground up rebuild of 2robotguy's easy as PI here http://www.thingiverse.com/thing:3817 this is actually a ground up rebuild as well to behonest it was just easyer to redesign then to take thew exisiting stls and modify them the http://www.thingiverse.com/thing:3817 had some flaws the locking ball inside of the container was a weak spot often breaking out of the model the inner tube on the model the security rings were angled and thus would not function proper and the models wall thicknesses where just to weak for me so to correct this i made the lids locking ring a solid square made the lid wall thickness thicker and and made the top ring slightly longer so the lid couldnt just be tilted off :) this container wil be used for a custom geocache container :D this model is a tight fit i gave the rings a very light sanding just enough to removes the ridges from printing on my relicator 2x and it fit perfect I printed with 0 shells 100% fill at .27 layer and it turned out pretty good :)
