Be Mindful - the small tabs can break off and become a choking hazard. Use caution and don't leave around babies or small children.

Sized to fit inside an empty game box.

You may need to cut the holder clips (for the game's instruction booklet) flush to the surface.

The design will hold best with the layer lines running across the ramps, so check in your slicer first.

The hold on the game is intended to be light enough to push the cards out with 1 finger, but strong enough that they wont fall out by gravity or a gentle bump.

I suspect the success of the spring flexure holding mechanism will vary greatly by filament type but what worked for me is below.

I printed with Creality Hyper PLA

Creality K2 with 0.4mm nozzle. I used .2mm layer height and think it feels pretty strong, and the wider steps give a sort of gripping effect with the corner of the game card.

I used really standard settings, 2 borders. The hinge is sensitive to layer directions, if the slicer makes them horizontal across the hinge then they will break easily.

I've included the 3mf for the single holder, so that you can check the hold and durability of the spring in different orientations with one holder before using more plastic with the full print. Maybe you'll come up with an interesting use for the holder in a different context.

This model is inspired by an excellent model I found by Samlai - profile here:

I just found myself wishing the cards didn't fall out so easily so I remade it with clips.
