Newton's cradle

thingiverse

This toy, known as a Newton's cradle, consists of a stand and five balls that fit in its grooves. To operate it, lift one ball at either end, transferring energy between them while the middle three remain still. Alternatively, lifting two balls will cause their counterparts to move. Print the "Newton's cradle" STL file once for the stand, and then print the "Newtion's cradle ball" STL five times for the balls. Ensure proper placement of the balls in the grooves for optimal functionality. The stand was designed in Open SCAD, with its code provided below: cube([50,45,5]); difference() { cube([50,5,50]); translate([5,0,0])cube([40,5,45]); translate([5,0,47])rotate([-90,0,0])cylinder(45,1,1,$fn=100); translate([15,0,47])rotate([-90,0,0])cylinder(45,1,1,$fn=100); translate([25,0,47])rotate([-90,0,0])cylinder(45,1,1,$fn=100); translate([35,0,47])rotate([-90,0,0])cylinder(45,1,1,$fn=100); translate([45,0,47])rotate([-90,0,0])cylinder(45,1,1,$fn=100); translate([4,0,47.5])cube([2,45,5]); translate([14,0,47.5])cube([2,45,5]); translate([24,0,47.5])cube([2,45,5]); translate([34,0,47.5])cube([2,45,5]); translate([44,0,47.5])cube([2,45,5]); }
