Description

Sometimes business is a knife-fight. This spring-loaded business card case deals your card in a flash while the other guy is still fumbling with his wallet. Push your card out nice and easy, or snap it out with panache. Either way, you'll close the deal.

Holds about 20 business cards. (Standard American 3.5" x 2")

Watch it in action:

UPDATE (12/17/16): I've improved the friction lock that holds the bottom part in place.

I've also uploaded the Solidworks files for anyone who wants to hack on it.

Infill:

20%

Notes:

Print at exactly 0.2mm layer thickness so that the blank space underneath the spring prints properly. Also make sure that the spring section is fully fused without any line separation. I recommend printing in PLA as ABS may not have enough stiffness.

Post-Printing

First use an X-acto knife to gently liberate the tabs and spring section from the rest of the top. Then remove the built-in supports on the exit slot. Take the leaf springs and press them into place in the slots in the bottom. Then press the slot cover piece into place. Finally, press the button piece into place. The button is not quite symmetrical, so orient it so that you get the most travel out of the button.

To load, first drop your cards (up to 20) into the top part. Slide a couple of cards about half-way out towards the back and then compress the leading edge of the leaf springs against those cards as you slide the bottom on. Make sure the bottom is completely seated into the top.

I destroyed the slide spring mechanism my first go because I was impatient and didn’t use an exacto knife as directed. Second go was much more successful and it looks amazing in the gratkit tri-color pla filament. I may print more of pressure spring strips in petg to see if it will make them a little more durable/springy.

I had to make some changes once off the print bed, and it mostly works. You have to get a feel for it. Pros: it can hold 20 cards! Design opportunities: 1. The only part of the assembly that stayed together without glue was the backstop on the top. All other pieces were too loose. It would be nice if these fit together without glue. Note, I did a flow dynamics and flow rate calibration beforehand. 2. More visual instructions would be greatly appreciated for assembly and post-processing
