About this 3D model

This pen cup fits in the cable grommets of my Uplift Desk. There is a version with a slot for cables and without. Having the lip at the top to keep it in the grommet creates quite a bit of wasted filament with all the support required but I really like the design and I want to avoid gluing it together for strength, so I've accepted it (if you have a more efficient idea absolutely let me know though).
