Viterbi Keyboard Case

Here's case design files for the Viterbi.

Case pieces

  • Switch layer (viterbi-switch.svg)
  • Bottom layer (viterbi-bottom.svg)
  • Middle layer (viterbi-middle.svg)

The exterior plate dimensions of these files are 145.55mm x 107.45mm.

Screws and Standoffs

This case was designed to use M2 screws and standoffs. The holes in the middle layers are for the standoffs, while the holes in the top and bottom layers are only wide enough for the screws. M2 screws and standoffs that fit the case can be purchased at Keebio: M2 Screws & Standoffs

Fabrication

Sculpteo

Sculpteo offers laser cutting services and is relatively easy to use.

Steps:

  • Upload file
  • Scale the object correctly, using the dimensions of the plates
  • Make sure all colors are set to "Cut" and not any of the engraving choices
  • Select your material and order

Ponoko

To have the case made with Ponoko, you can't take these files as is and send them off to them. First, you'll need to download the templates for P1, P2, & P3 sheets from here, depending on what vector editor you are using:

Next, open up the template of the sheet size you want and open up the case design files as well. Then, copy the drawings in the case design files into the template. Remove any overlapping lines to reduce the cutting cost using this guide: Avoid doubled up lines.

Middle Layer Thickness

If you're having the middle layers made, from the top of the switch plate to the top of the bottom plate, the minimium distance between the two required is 12mm if the plastic on the header pins is removed. The requirement is slightly more (about 13.5mm) if you leave the plastic on. Therefore, the following middle layer thickness are needed based on the thickness of the switch layer:

  • 1.5mm Stainless steel switch plate: 10.5mm
    • Usually accomplished with:
      • 2x4.5mm + 1x1.5mm layers
      • or 3x3mm + 1x1.5mm layers
      • or 4x3mm layers
  • 3mm acrylic switch plate: 9mm
    • Usually accomplished with:
      • 2x4.5mm layers
      • or 3x3mm layers
