About this 3D model

This is a remix with space for my favorite dental floss. I made this thing on SketchUp and Meshlab and I don't know why the design scale down on stl. So, you will need scale it 27x to obtain his correct dimension. When printing without raft I had some warp on the front corners. Only to not loose the long printing I made a support for it. It's optional but I liked the results. And I added an alternative for those that do not want a open floor.
