I've seen similar prints, but I redesigned this from scratch in Onshape and sized it for a pencil holder.
Print it in vase mode with 0.6mm line width at 0.2mm layer height for best results.
Tri color filaments look awesome.
If you want to create a variation of your own, you can copy the Onshape from here:
The author marked this model as their own original creation.
