I created this to help organize my pantry shelf where I keep long boxes of various items.
It is sized so that different shelves can fit different size boxes. Some are smaller than others.
I printed on my Ender 3 at full build volume. You must increase your travel speeds since there are a lot of long, linear moves. I used 100mm/s on my ender, but you could max out your extruder volume that way.
If you want to print it on a different printer, just scale Z height. For example the Prusa mk3 i scale Z at 80% (200mm)
