How to print the Y-BOX? Part 1

How to print the Y-BOX? Part 1


(parts BY01W45V02A, BY01W45V02A)

Printing the parts of the Y-BOX will make your 3d printer busy for a couple of days. But this is the only small price to pay for what you get: the worlds most color customizable,  extensible and lightweight enclosure for your printer.

The first things to start with are the joints.

It is possible to print all 8 joints at once. I suggest printing 4 joints – 2 pairs – 2 pieces of  A part and 2 pieces of B part.  Recommended material is ABS, but you will not be able to print it without an enclosure.  But don’t worry, PLA also works. PET also works well.

For the ideal strength, I recommend to print it with 25% infill density and with 3 perimeter shells. The necessary supports are integrated already in the model. Therefore no support material is needed. The integrated supports don’t need to be removed.  The supports will break consequently by tightening the bolts. The recommended layer high is 200µm. It is possible to print it with 300µm, to decrease the print time, but because of a lower precision, the tubes may not fit into the holes easily.

Vertical shells perimeters:  3 recommended
Infill density:  25%
Infill pattern: Grid or Cubic
Support material: no
Layer height: 200 µm
Skirt:  standard
Brim width: 0 (zero)
Material: ABS, PET or PLA


(regular edge covers part A BY03V01A and part B BY03V01B,  edge covers with holes BY06V01A, BY06V01B)

Cubes have 12 edges.  Due to limitations of the printer bed size one edge is split into 2 pieces. It means that we have 24 pieces to print.  This is also a chance to choose a color from three wide palettes of PLA filaments and make your own styled enclosure.  You can choose any color from the huge palette of PLA.  The edge covers will take the most of the printing time. Anyhow the fun is, that you can test maximal printing speed of your printer. The geometry and simple design of the edge cover allow using the max speed of the original PRUSA i3 MK3 which is 200 mm/s.  The printer fabricates the infill at the same speed as empty moves.

The edge covers must be printed with supports. The standard support settings in a slicer are OK. Printing one pair of edge covers is easy. Just rotate each cover 45° as shown on the screenshot. Slic3r generates supports automatically. They are drawn in green. More beneficial would be to print more covers at once. It is possible to position up to 7 covers on the bed.  Let’s decide to print 3 pairs which mean that in four runs,  we can have all covers printed. Because the Slic3r generates supports with a brim, it is necessary to turn off the skirt a position the edge covers very precisely. Look at the next screenshot how it looks like. With the Simplify3d,  positioning parts on the bed is easier because it makes supports without the brim.

Vertical shells perimeters:  2

Support material: yes

Material: PLA

    I just finished to print the edge supports, since the models are designed very nice printing went down smothly.
    Next step are the hinges. I really like the blue you used for the edge covers, which filament brand and color did you use? If I remember correctly they had a nice metallic blue look.

    In Vienna you also had a thermometer inside your display box, where did you buy it ?

    To sell a kit without printed parts is an awesome idea it delivers a very nie diy experience, thank you!

      Hi Rubi,
      thanks for your feedback and experience sharing.
      For the parts with the metallic look we used:
      Filament 1,75 PLA – pearl blue from “Plasty Mladec
      PLA Extrafill “Pearl Night Blue” from
      The thermometers are available on Try to search for “lcd digital thermometer hygrometer”

    Hi !

    I am just printing the edge supports but unfortunately in the supplied zip file the BY03V01A.stl and BY03V01B.stl
    are identical. The BY03V01A.stl file is missing. I tried to download the BY03V01A.stl standalone file in your shop but it also is identical with the BY03V01B.stl file. Please help.
