Here's a simple bunny rabbit model, just in time for Easter. Can be made from 3mm cardboard, or 3mm or 1/8" plywood if you want something more durable. Files are included for both thicknesses. (I have drawn a new, much improved set of six bunnies in six different poses that can be found here: https://www.designfind.com/project/43501-a-herd-of-bunnies)
Leave the parts attached to the kit card until you are ready to assemble.
As you remove each part, make sure to trim flush and clean up any little tabs left behind from where it was attached to the card. It is far easier to do this at this stage, while you can hold the parts flat on your cutting mat.
Use a sparing amount of white glue to keep the parts together. You really don't need very much, and it will keep your project much neater if you don't have big blobs of glue everywhere.
The back legs and hip are joined to the body. Make sure that the notches are fully seated all the way to the bottom. There should be no gaps left.
Assemble the remaining parts with a small bit of glue. Once again, make sure that they are fully seated into their notches. Let the glue dry with the rabbit sitting flat on its feet to ensure the feet are properly aligned.
Hoppy Easter, Little Bunny!
