shoe rack

I designed and 3D print a shoe rack with PETG, each floor has 2 bars 25cm horizontal, 2 bars 20cm vertical and 4 bars 13 cm as base for the next floor. The four base in each floor has Left and Right indicator and also front and back indicator. The front base also has support for mounting holes in case that someone wants to drill the rack in a wall. You can modify in more floors i print it only 5 floors. For better stability you can use hot glue or
