About this 3D model

When purchasing assorted kits of small electronic components from Chinese sellers such as AliExpress or eBay, it's common for these kits to be packaged in small plastic boxes. Unfortunately, those boxes are not easily stackable. As a solution, I have designed a simple rack that can assist with organizing these boxes in a more efficient manner. It is designed for boxes that are 125 x 68 x 21 mm in size and there are two versions of the rack available, with one designed to hold 6 boxes and the other capable of holding 8.
