Weekly Design Spotlight: The Geared Christmas Tree Spiral

This week’s selection is the Geared Christmas Tree Spiral by Cults contributor ENJOYREVIT.

Today is Christmas Day, and many readers will be busy under their tree opening presents. Hopefully, one of them will be a new desktop 3D printer.

Those new 3D printers will no doubt be fired up later today, and they will certainly need a good 3D model to print on them. That’s what this week’s selection is all about.

It’s a holiday-themed design with a twist. Literally, a twist: you twirl the bottom of the tree and a gearing mechanism spreads the flat tree into a beautiful spiral. It’s a magnificent design.

ENJOYREVIT, an “architect who loves 3D Design & Modeling”, explains how it works:

”There are gears inside the baseplate to make it easier to spread the tree. The gears inside are designed to accelerate 5x, so you can create a perfect spiral tree in a single rotation. All the bumps on each of the branches in the previous version are redesigned to make them more precise.”

Printing this item involves several components, all of which do not require support structures. One of the crucial components of the ensemble is a set of gears that are to be fitted at the base, however, the main star is the tree.

The tree is an intricately articulated piece, printed in place in a single operation, as depicted here. It is suggestible to alter the printing layers a few times to attain varied coloration for the fringes of the tree branches – a task executable on any standard desktop 3D printer, thereby eliminating the need for a printer capable of printing multiple materials.

And that’s all there is to it. The end product doesn’t need any motors or wires, just a composition of easily manufactured 3D printed components.

This is an ideal model for breaking in that shiny new 3D printer you just received. It’s available on Cults for download at the low cost of about US$3.
