Tiny Universal Joint

i have been working on a project and needed a very tiny universel joint that would suit my needs. after looking around awhile i could not find one. so i made my own ( i dont know why i did not think o this before ) and it works.
how it works is 4 purple conectors slide around a metal ball. simple as that. enjoy.

Supplies:

Step 1: Make the Sliders

place two purple rods on a blue stick as shown. ×2

Step 2: Put It Together

close a ball in between the two purples then repeat.
