This is a basic over-the-arm table intended for dollhouses. All-in one model can is simple enough your slicer should be able to cut off the top if you want to print separately. STL and 3MF have rotated this on it's “back” for printing to minimize supports needed. This is going to be a challenging print for most printers as the frame is to scale and thus pretty thin.
The author marked this model as their own original creation.
