Desktop Tool Organizer - Remix

I started printing this model (https://www.makeronline.com/en/model/Desk%20tool%20organizer/19680.html?trackModuleType=6) and didn't like all the infill it was needing, as I don't see the point of raising up everything so high. Recreated in Solidworks with about the same dimensions, except not so tall, because I didn't raise up the bases of the cavities any higher than the section with the lowest wall.
