I grew up in Memphis - and the Pyramid is an iconic part of the skyline. I couldn't find a suitable 3D model with adequate detail, so I decided to model one myself. The scale is roughly 1:1500 with the overall model dimensions, including the base, being 135mm x 120mm x 80mm. I have included two versions, one with ears, to prevent lifting from the bed, and one without. The ears can easily be clipped from the model after printing.
I printed the model in PLA with 0.15mm layer height and the level of detail turned out great. The model geometry is designed for a 0.4mm nozzle with no walls under 0.8mm thickness, so there are no single walls. Make sure your Z offset is dialed in pretty well as the first layer is a large square and requires a good level. In the future I may try to hollow the interior to cut down on the layer area and internal plastic use. Hope you enjoy!
