I appreciated KYZ Design's original shelf concept, but I preferred using zip ties instead of screws, so I added four 4 mm holes.
I intend to use the shelf as designed and give away free 3D printed toys at our local playground near our house. I left it without text so you can add it as a modifier in the slicer yourself.
I print mine with a 0.6 mm nozzle and use a layer height of 0.25 mm in PETG. For the text, I raise it by 1 mm and add a color change at the last layer of the text since I don't have an MMU. This will result in one layer of the entire shelf being a different color, but I don't mind.
The one in the picture is also about 25% bigger in width and height and the shelf is about 33% bigger to fit more or bigger toys.
The author remixed this model.
The only difference from the original is that this one has four 4 mm holes for zip ties instead of three holes for screws.
I think I am going to hang this on a wire fence and I thought maybe zip ties would work better.
The holes are just added with modifiers from PrusaSlicer so don't expect an amazing accuracy!
