This is a remix of OmNomNomagon's excellent low poly planter with a wide top.
I added holes to ensure proper drainage away from the roots, and tray to catch the excess water. I designed it so the tray fits firmly on the planter, but can easily be detached.
I also added a tray to this Low Poly Planter design.
I printed both pieces at 25% infill and no supports, and it worked out well
