Hinged Business Card Holder

This sharp looking business card holder includes a variety of hidden & slotted pegs underneath that can be used to attach a rubber band (of various sizes) in order to automatically pull the hinged arms towards the backstop, keeping the cards in place - even in a wind storm!

This model can be printed in place, and I found no supports were needed if I set the “Bridge Angle” in the Prusa Slicer to 45 degrees. (I also enabled the “Thick Bridges” option, but that may be optional.)

Would recommend printing this with a layer thickness of 0.10 mm for the hinge to operate the most smoothly, but it should also work fine with a layer thickness of 0.20 mm.

Here's a quick video I rendered showing how the hinge works:
