Wanted to put up my Monterosa, but the original design would not be able to fit my window or plant. Shelf comfortably fits a 4"/10cm planter. The part that hooks over has enough room for a ~3.8 mm thick bottom frame that is about 35 mm tall. You may need to pop this design into Blender to modify it to your own window before printing. I recommend a 0.6 nozzle and tree supports that touch the build plate.
