3D printing your own glider is a fun project. You can launch the finished glider with a rubber band and it flies far when you do. The 3D glider is easy to print and it is very sturdy. It is made out of ABS plastic with 2 solid layers. It takes roughly 40 minutes to print the glider. To assemble the glider you simply glue the tail, canopy, and hook to the main body.
