Numbers with TPU backing

Round numbers with separate TPU backing that the disks fit right in. My dad uses these to put on a basketball court to help number the places on the court for his players. The numbered disks fit easily into their TPU backing to help not slide around on the court. Good for other uses as well, numbering places in the yard, on a field for games, or spots to mark temporally. For outdoor use I would recommend printing in PETG.Boost MeNewish to the publishing world but love to 3D print. Help me support my habit!
