I use the Nicot queen rearing system to raise queen bees for my apiary. As anyone who uses this kit knows, the cassette holds 110 cups, but they only give you 10 or 20 bar holders and cup holders for adding the cups to the builder colonies.
This is the cell holder only. That's the piece that is usually cream colored and friction fits over the bar holder while holding the cell cup in place. The roller style cages fit over the outside. This is sized to the original Nicot system, not the Chinese knock offs you find on Amazon. I printed in yellow ABS, mainly because it was already in the machine, but PLA should work as well.
I have uploaded the bar holders as well in a separate "Thing".
