This is a pen for use in Juani_cer's thing #4808398. A super cool spherical joint that uses the flex of the plastic to allow movement of an axis along a spherical plane. This should be the perfect length to have the tip right at the focal point of the spherical plane. I haven't tested it yet but as soon I can print this and test it out I will update this thing.

update: I have shortened the pen to 91% of the original length. I have printed it and it now looks pretty good to my eyes. Should be good to go.
