Rhino Epic 40K (6mm scale) Remix/rescale 82%

Primarily a rescale of Fractalnoise's "Rhino transport vehicle for Epic 40K (6mm scale)" (thing 619993) to better match existing models. Rescaled to 82% and added a tab to hold the model while painting. Work done in 3dBuilder. Sliced with Prusa's custom version of Slic3r. Example printed on Oringinal Prusa I3 MK2 using Inland PLA.
