This model is my attempt at impossible floating table. Thanks to fishing line it looks like the top part is floating in space. The idea was sparked by this video:

Printing instructions:
 

Print 1x magic_floating_table_ring, 1x magic_floating_table_ring-2 and 2x  magic_floating_table_arm.

The magic_floating_table_ring and magic_floating_table_ring-2 have holes for strings in different positions.

Print with at least 2 walls and at least 15% infill.

Assembly:

If you have problems with the assembly try watching the video above, which explains how this trick works.

• Press fit the arms to the opening in the ring. If the fit is too loose try adding some super glue or paper shims.
• Tie a thin rope (can be fishing line) between arms through small 8 shaped holes. This will determine the overall height of the table.

• Measure three lengths of rope and tie them to te bottom ring. You should be left with something like this:

• Then tie the ropes to the top of the ring in matching holes. Try leaving some excess length so you can level the top ring. This might require some try and error. 
• Prepare a round platform from material of your choosing. Make sure it has diameter of 14 cm (~5.512 inches). I used some thin sheet of wood.
• Cut off excess rope and cover the top ring with previously prepared platform.
• Enjoy mind bending illusion :)

Update: Thanks to the keen eye of @DanielDenkov_2328218 I uploaded second version of the magic_floating_table_ring model. I forgot that top and bottom rings are not the same.
