Flatbox Rev 4 with Shadow Line

The focus of this design was to improve long-term use, especially with repeated assembly and disassembly. Using M2 heat set inserts over directly screwing into plastic is the main improvement.For aesthetic purposes, a shadow line was added to the part so that gaps between the cases from the imperfections of 3D printing aren't visible. Space for 6*2mm rubber feet inspired by SGFDevices's Bridget were also included.You may need to tune your filament flow depending on how dialed in your printer is. All parts don't need supports.
