About this 3D model

Ground inlets and curved downwards pipe for Modular Pipes System (found here) This is composed of 2 inlets 2x2 and 1x2 and 1 curved Pipe.I've attached a screenshot of the best orientation and support settings for FDM print of the pipe as its not the simplest one to print. Sample photo #2 shows usage of these with a Ground Connector box and plugs that are not included in this set.
