Poké Ball Riser Display Stand 150mm

My work colleague asked for a riser for his rear Poké balls collection in his display cabinet, so they sit higher than the ones in front for easier viewing. The risers have a recess to allow the Poké ball case to sit snuggly. This is printed in Black PLA Matte so blends well with the case. This riser is 150mm high, but I have also included both 90mm and 140mm
