Stack your favourite hotwheels or [insert other brand] with ease with these simple mini shelves.

My son asked me to make something for him to display his favourite hotwheels on a shelf so I made this.

They are stackable, so mesh into the one below for a very stable fit. This reduces the number of cars you can display by 1. So for instance, one shelf can display four cars. If you stack another one on top, due to the meshing, you can display 7 cars in total. I tried them stacked 4 high, and although a little top heavy, the meshing itself works well.

You can print in place, if oriented on its back with the shelves pointing up. The struts are about 34 degrees from the horizontal, or 56 degrees from the vertical. Your mileage may vary, but my printer had no issues printing this with Sunlu PLA+ without supports.
