Modular mini shelf / rack (22cmx10cm)

This is a modular mini shelf (that can also serve as a rack) for organizing whatever small objects or devices you might have. Since its original purpose was to organize routers and mini switches at home, it has a grid pattern for ventilation.

There are three different models: module with holes for the fits on top and bottom, the fits, and a final module with less holes to place on top. You can just assemble them with the fits, but if you need more stability, apply a bit of glue. Each level measures 22 x 10 cm, and there is a gap of around 6 cm between levels.

I suggest printing it with PETG / Rapid PETG if it's going to be used as a rack so it can survive the devices heat, otherwise, you can print it with PLA. 

The .3mf project already has all the configuration needed. The project's default filament is Rapid PETG, so remember to change the filament to whatever material you are going to use.

In any case, if you chose to manage the stl files on the slicer, this is the recommended printing configuration:

Quality

• Layer height: 0,24

• Wipe speed: 2mm/s

Strength

• Wall loops: 4 or 5

• Top shell layers: 4

• Bottom shell layers: 4

• Sparse infill density: 20%

• Sparse infill pattern: Gyroid of Cubic

Speed

• Initial layer speed: 30mm/s

• Initial layer travel speed: 300mm/s

• Outer wall speed: 140mm/s

• Inner wall speed: 210mm/s

Supports: I suggest printing the shelves upside down, with the grid touching the bed. That way, you will only need four small tree supports for each of the holes in the shelves that is not the top level

Others

• Brim type: only outer brim

• Brim object gap: 0,15mm
