Pencil Holder Variations
thingiverse
Found a nice piece from SNASA at https://www.printables.com/model/327316-wavy-pencil-holder-vase-mode and found the shape interesting for constructing a similar one in OpenSCAD. So I made two versions. (For the vertical striped version you may comment out the last rotate in line 30 of the scad file: "// rotate([0,20,0])") Although I did not print it, it has wall width 1.2 mm and is supposed to work vase mode. Be careful, the grid version is a bit computation-heavy if you use OpenSCAD, it took some 10 min to render.
