This model is an educational aid for learning the different animal groups. The main piece is the board with other supporting/matching prints made of animals that fit into these categories. I have not included the files to the animals but I would consider the animals from the following creators:
Dove - https://www.thingiverse.com/thing:182132
Turtle - www.thingiverse.com/thing:619805
Fish - www.thingiverse.com/thing:2057101
Butterfly - https://www.thingiverse.com/thing:35938
Frog - https://www.thingiverse.com/thing:3302391
Rabbit - https://www.thingiverse.com/thing:3708223
This educational aid could be used for any age but is designed with elementary grade students in mind.
This particular aid isn't currently avaliable to purchase but a similar aid was found to be $30 (Link Here). This item could be printed for a fraction of the cost if a printer and filament is already on hand. Roughly 12 meters of filament is needed to print a scaled version of this (45% scaled).
This project (excluding animals) takes roughly 4% of a roll. And using current prices for 1.75mm PLA filament from Matterhackers that would be 4% of $20. Which is roughly $0.80. So if a printer and filament is available then this project will cost substantially less than something that can be purchased.
