Christmas card holder

I cut a line down the mesh so it could hold a card. The wireframe may look a bit sloppy but it prints just fine. I don't know if there is an easier way to do this in a different program, i do know there are a lot more time consuming ways to do this so..

Also doubles as griefcard holder if you gifth this.

Some notes:
-Check the scale! The source file stands at about 15 cm , my pictured print is 9.4 cm high.
-Can be printed fine without supports at 0.4 mm nozzle.
-For folded paper
