I realize this is a very specific model, but I didn't find much online. I print all of my bases for display domes and now anyone can print one. This has much more character than a disc with a groove routed into it. It will fit a 4" dia. glass display dome.The only piece you might not figure out is the riser. It fits under the tray to help support it. PLA likes to move or sag with time and weight and this will help keep planes true. Domes vary and aren't truly round. You may have to scale the model up or down slightly after measuring the interior diameter of your dome.
