Julas Meec 18V battery holder.

notworthy setting would be a “brim” between 5-7mm. Mostly because printing things with such a small “build plate contact” seem to have a tendency to warp. 

Added “scarf seams”. You can see the result in the Matte PLA print.

OBS;
I went back to the PLA profile & added 5mm holes for fasteners. In the slicer you can delete or adjust those primitives. 
No added supports needed, It'll print the holes just fine. Personally I intent to just use dubble sided tape to fasten mine.

Happy tool organization!
