N-1 Math Summation
myminifactory
This is a math summation decoration that is from tc_fea on Thingiverse: https://www.thingiverse.com/thing:2516793. The pattern is created through the equation: Lines = n*(n-1)/2, where n is the number of points you want on the circle and the lines are the connection points. The files for n=6,7,8,9,10,11,12 are included. The printed photo files are for n=12. Printed at different sizes--the smallest is at 100% scale, the medium size is the size of an Ender 3 bed and the largest size is the size of an Artillery Sidewinder x1 bed.
