Print-in-place

The model does not need support material at all. The individual cubes are linked to each other and can wiggle around like there is no tomorrow.

In case the beads stick together, just rotate / move them a bit and they will get free.

Multicolor

Change filament at respective heights or use a multi-material print to achieve the multi-color look.

Detailed customizing instructions

• Download latest version of OpenSCAD, (See section "Development snapshots" at (https://www.openscad.org/downloads.html) )
• Download the "LetterCubesKeychain_V5_FourDifferentNames.scad" file from here.
• Open the .scad file in OpenSCAD.
• Change the variables to your liking:
  • To display the customizer, in the OpenSCAD "View" menu, the option called [Hide customizer] must be unselected.
• For fonts:
  • Set the fontname (and ensure you have that font installed on your system): fontname="Bangers";
  • The current font is “Blocktastic”, available online
• Press "F5" to get a quick preview.
• Press "F6" when you like the preview. This will render the geometry and takes a little time.
• Press "F7" to save the geometry to an .STL file.
• Slice and print the .STL file.

Some Fixes if you have issues with OpenSCAD:

1) Your font of choice is not found by OpenSCAD on your PC.

• In case you miss some fonts in OpenSCAD, download them from google: http://www.google.com/fonts
• e.g. for "Bangers" here: https://fonts.google.com/specimen/Bangers
• Install all the fonts you want to use. Then restart OpenSCAD.

2) OpenSCAD won't pick up newly installed fonts in C:/Windows/Fonts.

• In case new fonts are missing, put the font TTF files also in C:\Program Files/OpenSCAD/fonts/Liberation-2.00.1/ttf and restart OpenSCAD again.
• Alternatively, put them in C:\Program Files/OpenSCAD/fonts/Lib
