Wobbly letter cube keychain (configurable)

A keychain with your or your family/friends first name, written in individual letter beads. The beads are connected flexibly with rings and move after printing. Its also nice for fidgeting. 
Note that this model is print-in-place, so no support material is needed.

STLs for more than 1200 first names are included. Scroll all the way down to “other files” to get them as ZIP file.

Also there are several examples included, where the beads show 4 different words:

• print -  layer - build - dream
• tiger - horse - zebra - otter
• love - kiss - wish - hold
• silence - balance - essence - journey
• Lucy - Jake - Emma - Alex
• … and you can create your own using OpenSCAD, like first name, last name, etc.

Update15.10.: Customizer in OpenSCAD optimized to easily define one or four words.

Customizing

The 4 names shown are configurable with OpenSCAD. To do that, please install OpenSCAD on your own computer and follow the detailed customizing instructions below or follow these in depth instructions.

You can either show the same name on all 4 sides (all="Franziska") or 4 different words (text=["Print","layer","build","dream"];). Just the first word however is setting the number of characters, so put the longest word first.

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 1mm and 10.2mm to have the multi-color look of the print shown above:

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.
  • Alternatively, change variables in the code: You find the variables in the beginning of the .SCAD file:
    If you want the same text on each side of the cubes:
    text=["Franziska","Franziska","Franziska","Franziska"];
    or if you want different text:
    text=["Print","layer","build","dream"];
• 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

Reworked the chain to be integrated completely into the cubes for a neater look. However, it will not bend as nicely and rather wiggle around, which is also nice.
