Generate an STL using a Mac and then print
<b>Update</b> I created a simplified version so that I could generate the STL file, it's a little too large to print, please scale by 0.75 to fit the build platform of a Makerbot.
I also moved the loop up to the mid point to reduce the overhang (that's the blue one printed)
I've tried to use parameters for everything you might want to change:
<b>axisRotation</b> the number of times around the top of the torus <b>radialRotation</b> the number of times rotated into the hole in the torus <b>baseHeight</b> height of the plinth (0 for no plinth) <b>numberOfSpheres</b> number of spheres used to complete the knot <b>sphereQuality</b> the larger the number, the lower the quality see $fs <b>majorRadius</b> the major radius of the torus <b>minorRadius</b> the minor radius of the torus <b>sphereSize</b> the size of each dot in the knot <b>cupHeight</b> number of links high <b>vStretchFor3dPrint</b> how much to stretch it up to help with overhang <b>printWidthInMM</b> the width you'd like the finished item to be in millimetres
This is based on the Parametric Knot thing I made previously, ...and the bracelet thing (notice a theme, I promise I'll stop soon :)
I had to do the knot thing before I could produce the cup I wanted, and it turned out nicely, so I published it.
