As a request I have uploaded the STEP file for you to download and modify as you so desire.
Inspired by parallelgoods's fantastic design of the Self-Watering Planter, I wanted to make a square version as it suits my needs better for my herb garden.
There is also a small window at the front of the planter to label what you are growing.
This version is about 70% the size of the inspiration size. For printing settings and sealing tips I recommend checking out, thing:903411. Cheers, and happy print/planting.
