This is a vase/pen holder inspired by a helical-toothed gearwheel in motion artistically simulating the deformation (hence the wording "4D" ;-)).
If you like this design, please consider buying me a coffee to support me in the creation of many other useful designs as a sign of gratitude for the huge amount of time and effort. Thank you very much and happy printing!
