This is a box I made to hold a gift card for my sister in law. The goal of this was to be a pain to open. If printed in TPU the only way I found to get into the box is to cut it out. It also works well with ABS and PLA.
Enjoy this thing as it is first upload and probably my second design ever.
I printed without supports but the cross members might come out a little more cleanly if you use supports. My goal was to make this print fast and be a pain to open, aesthetics wasn't much of a concern.
I created this using Tinkercad. It might be my second or third design ever so the fact that it printed is pretty neat.
