Beginner shapes: your first printed cookie cutter

Your first printed cutter should not try to prove anything. Its job is to show whether your chain — description, preview, slicer, printer — works end to end. A circle is better for that than a dragon: if a circle cuts badly, the shape is certainly not the reason, so what is left is wall thickness, edge height or dough temperature. That is exactly what you want to isolate at the start.

When you check the preview, look for three things. Is the frame closed all the way round? Are there sections noticeably thinner than the rest? Is there a slightly wider rim at the top to press on, so your hand never touches the blade? If those three are right, the rest is slicer work: three to four perimeters, 15 to 20 percent infill, 0.2 mm layers, PLA, no supports.

Then comes the step most people skip: the test biscuit. One press tells you more than any preview — whether the edge separates cleanly, whether dough sticks inside, whether the height suits how thick you roll. Only once a plain shape goes through does the sitting cat become worth the credit. All six shapes below are deliberately dull, and that is precisely why they work.
