This is one of the emoji ornaments I designed for the Sindoh Decoration Contest of 2018. It will take about 45 minutes to print and is about 3in x 3in. The ring is 10mm in diameter (outside) and 2mm thick. Thanks for checking this out, Merry Christmas! I also designed a tree that is printable that these fit on, fell free to check it out, its name is Giant Christmas Tree.
