Key Card Swipe Pad

thingiverse

My kid was fascinated by a YouTube video showing kids using key cards to unlock doors, so he begged me to create one. I managed to whip this one up in no time. Printing it at .3mm resolution was lightning-fast, thanks to my child's impatience, allowing for a lot of room for improvement. The card is kept in place with sticky tack, making it easy for him to move it between different doors. I made two holes that fit standard LED Christmas lights, as it's the holiday season and those were lying around. To turn this into a light-up card, I simply drilled two holes behind the inserts and connected two lights to an on/off switch.
