class DrillStand(Boxes):
"""Box for drills with each compartment of a different height"""
description = """Note: `sh` gives the height of the rows front to back. It though should have the same number of entries as `sy`. These heights are the one on the left side and increase throughout the row. To have each compartment a bit higher than the previous one the steps in `sh` should be a bit bigger than `extra_height`.
Assembly:
Start with putting the slots of the inner walls together. Be especially careful with adding the bottom. It is always asymmetrical and flush with the right/lower side while being a little short on the left/higher side to not protrude into the side wall.
| | |
| ---- | ---- |
|  |  |
| Then add the front and the back wall. | Add the very left and right walls last. |
