This is a set of helical gears which mesh at 90 degrees to each other, along with a stand to keep them in place!
I designed everything with very loose tolerances so you don't need an extremely precise printer for the gears to work!
In the pictures, the stand was printed in Fillamentum Vertigo Grey, the two gears were printed with Extrudr Glow in the Dark PET-G and SUNLU Rainbow Silk PLA+ and the bushings were printed with Eryone White PLA.
To assemble, place the bushings in the slots of the gears and gently stretch two opposite sides of the stand and slot the gears into place.
Hope you enjoy and happy printing!
