Improved Star Wars Legion Walkway Base Level

Also available on Makerworld. I'd appreciate it if you download it over there because, well, Makerworld rewards designers for downloads and Thingiverse does not.
This is a remix of TabletopOddity's awesome Star Wars Legion - Modular Walkways & platforms. I modified some of the "base" components so that they can function as a middle(or top) level instead of only as a base. In addition they actually perform their original function as a base slightly better than the the original model. Like the original, it prints without supports.

Modifications: I added one slot to each corner of the component and also narrowed all of the slots.

Note: The original model is marked CC-BY-NC, but the public Tinkercad file is marked CC-BY-SA. I followed the Tinkercad file's license in posting model.
