I am seeing a lot of low poly candle holders on thingiverse for printing but would like to make my own. I haven't seen many tutorials. Can someone point me in the right direction to make something like this http://www.thingiverse.com/thing:18672
Just add the modifier to the choosen cross-section shape (an exagon for example).
With the options provided you should be able to easily control many aspect of the shape such as the overall height, the number of steps and the number of turns.
Then you could stack a Triangulate modifier for a better control upon the way non-planar faces are splitted.
Add a Circle with 6 vertices and extrude it (E). Subdivide it adding edge loops (Ctrl+E). Snap the cursor to the top edge loop (Shift+S-->Cursor to Selected). Enable the proportional editing, increase the editing ring with Mouse Scroll and rotate (R) the top edge loop as pictured below.
Start by adding a cylinder and adjust the vertices count to 6 in the operator panel
Next, add a simple deform modifier and set it to twist. Adjust the angle as desired.
Add some loop cuts with Ctrl+R (I added 5), and delete the top face in edit mode. Add a solidify modifier as well if desired and adjust the thickness as needed.
Following these steps, you should be able to achieve this kind of result:
