Not a direct remix since I used the “slotless” version (https://www.thingiverse.com/thing:4817715) that already served as a base model to HollandJim. 

I just needed another divider as a “pillar” for a printed tray insert and wanted to keep access to the area below the tray possible without having to remove it every time. So I removed most of the main body and only left the side rails and top piece. 

If you want to print it, I'd highly recommend that you use filament that's more resistant to higher temperatures than PLA. I used PETG, other good choices should be ABS/ASA and similar.
