Twisted Hexagonal Pen Holder

This is a remix of the Twisted 6-sided Vase Basic by MaakMijnIdee. I made the hexagon by intersecting six large diameter circles so the edges of the hexagon are slightly convex. If you like the faceted look of the original, you can reduce the number of slices in OpenSCAD on the linear twist extrude. Finally I actually subtracted a volume from the middle, so it prints as-is from the STL file. The original required you to specify the number of side and bottom shells and then select no infill (a mistake I made when trying the original).
