Printed Business Card Launcher

thingiverse

The business card launcher can be printed in its physical form. It efficiently launches various cards such as business, playing or metro cards but be cautious as it is powerful. To follow the instructions, refer to http://thingiverse.com/thing:18125. The required items include 1 x 1/4-20 x 1" Bolt, 1 x 1/4-20 x 0.75" Bolt and 2 x 1/4-20 Nuts. Assembly involves using the 0.75" bolt to connect the grip to the camera mount as the hole in the latter is slightly undersized. The 1" bolt is used for connecting the top with the camera mount. To launch a card, thread a rubber band through the square holes and tie a knot. Hold the corner of the card in the loose end of the rubber band, stretch back and release to fling!
