Rubber Band Gun Business Card

thingiverse

Last week, I discovered that my business cards weren't impressive enough for an upcoming networking session in KC. To make a good first impression, I designed a unique 3.5x2-inch card that transforms into a functional rubber band gun when snapped apart. Check out this video of it in action: http://youtu.be/InnUcXhVeN0. The cards are made from 0.06-inch thick Delrin or acetal and can be customized with color using a dry erase marker. Detailed assembly and operation instructions are provided, and I'll even distribute regular business cards with the instructions for easy usage. For those who want rubber band business cards, #10 or smaller bands work best, which can be found locally or ordered online from McMaster. If interested, feel free to contact me at craig@built-to-spec.com for custom orders. Excitingly, you can now get your own by visiting http://builttospecstore.storenvy.com/products/330223-rubber-band-business-card. I've recently released a revised version (rev b) with improved spring mechanism and easier clip insertion for an even better user experience.
