Description
My son watched a YouTube video of some kids using a key card to open doors so he asked me to make one. This one turned out alright. I printed it at .3mm pretty fast, because children are not very patient, so it could look a lot better. It is held in place with sticky tack, so he can move it to differnt doors easily. I made two holes which fit your standard LED xmas lights, because its xmas time and thats what I had laying around.
To make the light up one I just drilled two holes behind the inserts and hooked two lights up to an on off switch.
