Catapult

thingiverse

If you'd like to change the shape a little, download the DXF file below. I suggest keeping the bottom just as it is. The extension at the front is designed for your hand to hold it down so it doesn't flip over when launching things. You may keep it if you want it. Try to maintain the same height so the top spacer section remains in the same spot. To assemble it, place one side flat on the table. Put the dowel into the circle hole and the bottom spacers in with the divot facing down towards the bottom of the catapult. The top one goes in with the divot facing up towards the top of the catapult. Place one circle onto the dowel, then the arm with the larger divot facing up and make sure it's in the back of the catapult, followed by the second circle. Glue everything in place except for the arm, which you want to move freely with the circles keeping it centered. Place the other side on top and line it up to press everything together. Glue the other side on. Attach the squares onto the larger divot on the arm in an L shape to hold things being launched. Loop a rubber band around the bottom front spacer, then over the top spacer and around the arm onto the small divot. Enjoy! Be safe with the catapult! Do not launch at others. The DXF files include everything you need. The side needs to be copied for another one. The middle section needs to be copied for a total of three. The square needs to be copied for another one. A wooden dowel 1.6 inches in length and 0.36 inches in diameter (which can be easily changed) is also needed. It's designed this way so you can make modifications as desired, then copy instead of having a cluttered workspace and deleting extras before copying. The AI document has everything neatly arranged and packed in the corner, ready to be cut out.
