Rotary Motion Stamp Machine
Personalized stationary at the push of a lever
I began with the goal of stamping a standard 2” x 3.5” business card with a personalized logo. Inspired by a traditional crank and slider mechanism, I designed, digitally fabricated, and ultimately manufactured a device that produces custom stationary with a single push of a lever.
The Challenge:
Design, digitally fabricate, and build a mechanical stamp machine that incorporates the use of rotary motion and spring actuation. The user should be able to stamp a 3.5” x 2” business card in the same location each time while the stamping mechanism resets to its initial position on its own after each actuation. The stamp must move in a linear fashion and travel at least 2 inches; must be operable with one hand (no additional stabilization required); mechanism must fit within a 10” x 4” x 8” volume.
Materials:
1/8" thick acrylic; 6-32 x 3/4" machine screws; 1/4" steel collar set screws; 1/4"D x 6"L stainless steel D-shaft
Skills Used:
Sketching, rapid prototyping, 3D modeling (Fusion 360), laser cutting, captured nut assembly
Result:
A fully functional spring actuated stamp machine for personalizing business cards!
