Description
My child's biology class needed an eyeball model. I originally just wanted to make a simple spherical shell, but then it needed a variable iris and lens
I had previously printed a fidget toy by another author (https://makerworld.com.cn/zh/models/441800-hong-mo-ji-gou-jie-ya-wan-ju#profileId-358357), so I decided to make a shell to put that toy into. The result was such a huge eyeball, its size is suitable for a teacher's teaching aid
Everyone can directly print the shell. For the cornea, I used the lid of a Sam's Tiramisu box
For the lens, I added two pieces of cling film. The syringe and tubing are from a feeder that my parrot didn't use when it was young. Everyone can adjust the groove according to their own tubing conditions. I used hot melt glue for connection and sealing. Although the sealing effect is not very good, it's sufficient for demonstration purposes for now
