100% vase mode modular drawers

I couldn't print the drawers from the original design in vase mode, so I created my own version. Additionally, I designed a sleeve with tabs to prevent the drawers from being pushed in too far, which also improves bed adhesion during sleeve printing. This updated design is fully compatible with vase mode, although you can still print the sleeves in standard mode if you prefer more rigidity. The outer sleeve is a modified version of the original file and remains compatible with the non-tabbed version. If you'd like to leave an empty space and use a sleeve for support, this option is available too.
