Polygon-Möbius-Strip Customizer

thingiverse

Takes a regular polygon and revolve it about an axis exterior to the polygon, creating a toroidal solid, while rotating the polygon about its center as it revolves. Customizable, so you can change: number of polygon sides 'N_gon' number of twists 'Twist' per ring rotation Ring and polygon diameter Thickness (for Möbius Strip only) angular section to print Rotation orientation of polygon Internal thorical hole (if any + diameter) Some examples: mobius_polygon(N_gon=n,Twist= 0) is just a non-twisted ring (toroid) with an n-gonal cross-section and approaches a torus as n goes to infinity. mobius_polygon(2,1/2) is the classic Mobius strip. mobius_polygon(6,6), has n-surfaces and n-eges, all identical, spiraling around each other.

Todo list: DONE: add option to print just a slice => implemented mypie() *DONE made a bit faster using children() DONE: added smoothness by hulling every 2 items. ... (comment if you have suggestions) DONE: Published some STL derivatives How I Designed This Openscad
