Shelving unit for component boxes

The main feature is that the shelves can be stopped at any location on the shaft, and you can print as many of them as you need, with different sizes too. The shaft is stackable, so it can go higher than 60 cm (that you can see in my pictures), but that would be too wobbly. Or it can be shorter.

Several versions of the shelf sizes are included. For other sizes, use the F3D file and modify the user parameters “ShelfPegDistance” and “ShelfDepth”.

Printing should be optimized for strength. There is a lot of mechanical stress on the shaft and the foot because all the shelves are in front of the shaft. So, it's best to lay everything down on the print bed horizontally, and the foot parts on their sides so that forces are applied along layer lines and not across them. Unfortunately, this orientation requires supports; I used dual-material PETG+PLA printing on the XL for zero distance supports to get well-fitting parts.

Sample orientation and supports:

Some M3 set screws are more-or-less required to connect the shaft pieces together. 2 regular M3 hex cap screws are needed to connect the foot parts to the bottom shaft piece.
