Hyperboloid Hexagon Pen Holder Cup for Brush Pens

This is a pen holder designed for Brush pens but could be used for just about any pen.

The pens I use are Tombow Dual Brush Pen Art Markers. 

     These ones here.

This arrangement is called a hyperboloid.

Each pen hole depth is  101.5mm ( 4 inches ).

Each pen hole width is 10mm ( 0.4 inches )

The internal cup depth (without pens) is 87.25mm ( 3.43 inches )

The internal cup width is 80mm ( 3.15 inches )

Overall, this thing (without pens) is about 185mm Wide and 93mm Tall ( 7.28 inches Wide and 3.66 inches Tall )

The print job will take approximately 262.57g of filament.  ( when sliced with a .2mm layer height, 15% Gyroid Infill, & 2 walls )

And approximately 9hours 20 minutes.

When I printed mine, I printed with 0.2mm layer height and 5% Gyroid infill, and 4 walls.

      (Printed awhile ago on my original Ender 3.)

Then I drilled a hole in the bottom, poured a bunch of BB's in, Then filled with epoxy.

This made it nice and heavy.

No moving around on my desk.
