doom keycard card holder

I wanted an old school doom keycard holder for my work security card. now I can badge through doors in style. I modified the original file so your card slides into the back. I increased the depth on the back detail so it prints cleaner. I raised the 3 dots on the front so they can be printed in a different color easily. I print it with supports everywhere. It's a bit of a pain to get the support material out but I do that so I can print it in 3-4 colors. I used 2 tones of red in one card and it turned out really nice.
