[3D Printing Application] A Real, Firing 3D-Printed Crossbow!
The adult toy is here! The 3D-printed crossbow is put to the test. This ultra-miniature crossbow can not only be fitted with arrows but also fired. It has all the real functions and can even shoot at targets! The download link is at the bottom of the article. Gather your friends for a competition! This crossbow uses the elasticity of the PLA body to drive the elastic string for shooting. Let's see how it performs:
First, we put the files into the Ultimaker 3D printer. All parts were printed in 6 hours. Since the crossbow has many interlocking components, it is recommended to choose the highest precision for 3D printing to make assembly easier.
First, put (2) into (1), and (4) into (3); then snap it into the body of (1), making (4) a movable slider, which is the original component for cocking. Next, component (1) has many small holes for assembly, where clipped paper clips or styrofoam glue can be inserted for fixation.
Next, attach (5) and (6) to the left and right sides of the main body respectively, then snap (7) into the rear for fixation. The basic shape is now complete, and the trigger at the back is indeed the firing controller!
Once the internal structure is complete, the exterior assembly is relatively simple. Install (8) on top, (9) are the fixing devices for the front of the main body and both ends of the bow, and (10) are inserted into the left and right side slots as shown in the picture to complete the main body!
Everything is ready except for the elastic string. We recommend using an "elastic string" that is somewhat thick and round. There are small holes at the ends of the bow on both sides. Pass the string through one side's hole, tie a knot, then pass it behind the central slider, wrap it around to the other side, and tie another knot, and you're done!
The completed crossbow looks super cool just sitting there. Our colleagues had a blast playing with it. You can print targets in various colors for a competition, making it a unique tabletop game. Before firing, remember to push the slider to the front so it doesn't obstruct the elastic string! Now, turn on your 3D printer and print your own crossbow!
Please note: For the arrows, we used toothpicks. We remind you that the mini crossbow has considerable actual firing power and a long range. If there are children at home, we recommend using cotton swabs instead to avoid any danger.
