About this 3D model

Around half the size of a 1kg filament box, print two and it will be the same size as the filament box (at least the same size as the one that i use) 20.5 X 10.5 X 2 cm my storage box had a bit of space left next the filament, (not big enough for another filament) so , desined this slim case to put the Silica Gel in it. maximizing the space usage in my dry box. there is also a notch at the end, so it will latch close =================== the walls are 2mm thick.1mm think will also work, which will reduce the print time by 2 hours per piece. so for the top+bottom, it's a 4 hour saving! the way that i did it, is to move it 1mm bellow the bed in cura. but obviously it will be a bit more flimsy , also the top will not be flush on the box, since there will be 1mm missing on top, but not a major issue. do not do this for PETG, since it will probably pop open , since it is more flexible. ====================== freecad 0.18 file also included
