Introduction: Mini Disk Launcher
This is a fun project made by a kid for kids. This is a mini disk launcher built out of cardboard. It is a Kid-Friendly project that can be quickly and easily made with simple materials from around the house. The disk in this project was my first time ever designing something in Fusion 360 (found as Body2.stl for download). It is 3D printed, but it could easily be substituted with a coin or other round, flat object. I am a student at New London Academy and love learning about STEAM projects.
Supplies
Supplies are all things that can be found around the house- Cardboard, scissors, rubber bands, tape, a disk (or coin or other flat, round object) and a ruler (Optional).
Step 1: Cut Out Pieces
Cut out 4 pieces of cardboard, two the same size for the front and back, and two thin strips to go in between. This can be eye-balled or cut precise. My main pieces measure 5.5 inches x 3 inches, with the strips measuring 5.5 inches x 1/2 inch.
Step 2: Attach Middle Strips to Back
Tape the two strips onto the edge of the bottom piece. I used making tape, but any tape could be used. Hot glue could also be used.
Step 3: Cut a Hole and Attach the Front
Cut a hole into the top piece using scissors or a blade. My hole measures 1.5 inches x 1.5 inches. Tape the top piece onto the bottom piece, wrapping the tape all around to make sure it is secure, and also making sure not to cover the hole.
Step 4: Cut the Middle Piece
Cut a piece of cardboard that will easily fit in between the layers of cardboard, but is still long enough that it will stick out the bottom. Mine measured 5 inches x 2 inches.
Step 5: Cut Slits and Attach Rubber Bands
Cut two little slits in the bottom of that piece, and two slits on the side of the main piece, shown in blue in the picture. This is where the rubber bands will be inserted. Insert the middle cardboard piece into the main part. Attach rubber bands by inserting the rubber band onto the main piece first, followed by inserting it in the bottom slit in the middle piece. Repeat on the other side.
Step 6: Insert Your Disk Into the Hole
Your disk launcher is ready to make something fly! Print your disk using the attached file, or find another round flat object, and insert it in the hole.

Step 7: Pull Back and Watch It Fly!
Once you pull back on the middle piece, the disk will drop down and land on the bottom layer, and when the middle layer is released, the middle layer will push it out and the disk will fly through the opening and soar across the room! Make sure to watch where you launch it, as the disks are small and can be lost easily. Enjoy your new creation!
