this is a set of stl files for 3d printing a portaloo in 1:16th or 1:14th scale for RC  trucks/crawler meetings etc.
 
This can be printed in pla if for indoor use but high temperature products are recomended for outdoor use. A 0.4 mm nozzle with a 0.2mm layer height is fine for most of the components but the roof is best printed with the smallest layer height you can use.
