⚠️ Small hack

To keep it support-free, the mounting holes have a thin top layer.
After printing, just poke it through.

Notes

This is designed as a real workshop solution, not just a display model.

If you need more space → add more rails
If you need different storage → adjust  the drawer, or let me know :-)
