Hex pen holder extended

Love the design idea of the original creation, but needed to extend the number of possible pens and also extend the height of the lower pen slots. Cura slicer were also whining about the original STL file, had something to do with the first layers.

So, I really did not tinker the original STL file, but merely started from scratch with Tinkercad. 8 rows and 11 columns, where the pen slots are starting at 35mm height and then incremented in steps of 5mm up to the back ones at 70mm. 42 pen slots in all. Think it came out quite nice!
