Summary

This self-designed planter shelf is ideal for mounting on walls. For optimal results, print the drain nozzle and the shelf separately and then glue the nozzle to the shelf. The shelf features a back-end lip, creating a slight backward tilt to direct water towards the drain hole. A small rubber hose can be attached to the drain nozzle, leading to a catch cup below.

Update: Included files for a small planter with mini removable planters.
