Hi

I try to build some toy in freecad

If does anyone have any experience

So the object has a cylindrical cavity in which after printing I will put a cast metallic cylinder. What the diameter of the hole I need for cylinder with 10 mm diameter to sit tightly in the socket but not to bursting material, in other words, perfect. 10mm or with minus?

Question 2

Not very expensive printer and plastics good for mechanic details printing ?
