Pen Holder Cone Type

A reimaging of my rectangular pen holder. I reused the 20x20 holes and angles, but the model is more efficient, holding more pens and printing in about half the time. The model I'm uploading here has 5mm deeper holds than shown for the ink cartridges.

Print each piece on the broad side, no supports needed. I recommend printing the first layer at 10mm/s instead of Prusa's default 20.
