This is 2 parts plate rack. It can be easily assembled, just plug in one part to another part.

It was printed by P1S and PLA Basic.  The support is enabled and wall loops is 3 to make the parts stronger.

I have added a new assembling version with all parts in one plate and you can assemble it by yourself for fun. The 22 short rods need to push in the holes for the plate rack and the 4 long rods need to push in the holes for the bottom frame connection. Please finish the bottom frame connection and then push in the short rods.
