Cut the parts out with pliers, nail sissors or hobby knife. The assembly is easy and self explanatory. The parts should fit together tightly, but you can always use a bit of super glue to secure the parts together. If you don't need the frame I uploaded the model without it. Please keep in mind that the fine texts and details require very fine lines on the first layer so you need perfect bed adhesion. I recommend to use some adhesion spray like 3dLac. Stay tuned for more kit cards! Have fun printing it!
