Added a #SketchUp model to my #3DWarehouse, of a 30" wide x 12' long x 24" high raised bed box planter. Not especially cheap, but is made from readily available items from home improvement retail.
Note that the soil has hidden faces with the goal of keeping a solid so that soil volume can be measured by selecting the solid.

Not sure whether to drop this into #SketchUp #3DWarehouse. My instinct says no.
My newest 3D model in the 3D Warehouse (it's been a looooong while) of galvanized 3/4" corrugated metal. Sure, there are lots of these, but this one is hyper-realistic with texture of corrugated metal.
You can skip the photorealistic renderer! No need to have a fancy pants 16-core CPU with 64GB of RAM and 2TB SSD just to make pretty images.
