Since I bought the awesome uranium necklace from overflo of the hackerspaceshop ( https://hackerspaceshop.com/collections/art-and-beauty/products/uranium ) I wanted to make a custom body for it. So I designed it to be made on a SLM machine (3D printer for metals).
I made two variatons, one in the original triangular shape and a hexagon shaped one.

I know there aren't many who have access to such or similar machines but I am sharing it anyway, I hope anyone can use it somehow or remix it.
The print settings are not really helpfull, I know. :P

My design uses the original rubber foam part as an isolator between the PCB and the metal case.

Read more about it on my blog: https://regendrogenbogen.wordpress.com/2016/06/13/uranium/
You can get both designs also on shapeways:

SLM machine








Just print the thing on your own SLM machine in Aluminium.


support removal

Remove the support using a hammer and chisel and eventually a dremel. Then simply sand- and beadblast the part to get a nice surface.

finishing touches

Drill out the 3 holes on the bottom with a 1,6mm drill and cut a M2 thread.


Cut the back board from 2mm acrylic or any other material with the same thickness.


Put the marble in the cage and add an O ring behind it to seal it optically.
Then insert the original foam rubber isolator and put the PCB into the pocket.
Put the back board in place and lock it in place with 3 pcs. M2x4 screws with washers.
