I designed this to hold 3oz Walgreens Brand bath cups secure for propagating African Violets. The cups are secured in the holder at the first ring. This prevents the cups from falling over or bumping into each other when you place them in a gallon Ziplock bag. I printed in PETG due to the humidity in the bag. Slice with the feet facing up.
