3D cup pen holder

This pen holder wants to be a nice tribute to 3D printing, to the satisfactions it has given me but also to the headaches I have had over the years with it.to be printed without supports any printing defect that will be created is welcome :).the idea for this model comes from a file seen on Thingiverse: https://www.thingiverse.com/thing:5626173of which I wanted to create my own version.
