- 15. TinkerCAD Steps 1. select shape & copy twice 2. Base plate (Height: 2 mm; Size: desired + 2 mm) 3. Solid body (cookie-cutter height: 15 mm) 4. Hollow body (Size: desired - 6 mm) 5. Select all three bodies and centre them on x,y 6. Group all three shapes so that final product is visible in a single colour Christian Voigt (ZSI) 15

Causes • Warping: Outside versus Build plate temperature (60 – 100 degrees) • Spaghetti: Callibration and levelling in three dimensions • Printer lapses: Layer height, printer speed • Droping shapes: challenging object geometry (‘overhangs’); usually support structures are recommended with Christian Voigt (ZSI) 35
