Free

4mm_6mm_8mm_10mm_12mm_14mm_16mm_18mm_20mm - Step Mandrels Mandrel 1 starts at a 4mm Circumference, then steps up in even increments to a 6mm Circumference and ends with an 8mm Circumference.  Mandrel 2 starts at a 10mm Circumference, then steps up in even increments to a 12mm Circumference and ends with an 14mm Circumference.  Mandrel 3 starts at a 16mm Circumference, then steps up in even increments to a 18mm Circumference and ends with an 20mm Circumference.  Each Mandrel is 150mm High.   Perfect for 3D Metal Model Building like Metal Earth, Piececool and other brands.  Print the even numbers one color and the odd numbers different color. Print them at a 50% infill  Keep checking back. I plan to make all kinds of tools for 3D Metal Model Building. So I will be adding more in the future.
