Pen holder/stand 8mm to 22mm diameter (wacom or other)

thingiverse

Stand for various pens (mine is for wacom tablet, but could be for regular pencils as well), support various diameters. Parametric desing (solidworks sources included). Many configurations for various diameters provided, but feel free to reach out if you want more configurations. For me when I was printing I used 0.5mm bigger hole than my pen is (to compensane for printers overextrusion and the fact that the circle is just N-polygon and not perfect circle), but that cause very snug fit, the pen can be inserted only when perpendicular to the holder. While printing 1mm bigger will make the pen being straight but give more margin to insert the pen in a non perfect angles. The holder needs about 17mm clerance between the start of a tip cone to the first wacom buttons. The cone height is calculated depending on the diameter but after that the holder needs a straight shaft for at least 17mm and not being interfered with buttons. All pens I tested with (3 wacom pens) have much higher clearance than this so it should be ok.
