Designed to print without support. This ornament would look great anywhere; a Christmas tree, a window, a bulletin board. Approximately 105mm in diameter.
Print out both peices. The main petal section has shallow slopes and will look better with .15mm layers or less. The uploaded picture is at .13mm layers and 19% rectilinear infill. If you have a heated bed and are using ABS, keep it cranked up for this print as the petals tend to peel up. There is also a 'peel resistant' file with mouse ears.
The core snaps into place, but you may need to scrape off some plastic from the first layers to get the proper clearances.
