Model made with space for a 3mm LED light inside the top lid (see pic 3)
I printed the star and put it inside a cut flat 5ml siringe tube filled with transparent silicone then epoxied the top and bottom lids on.
Pictures have a different bottom lid because i got it missprinted and had to improvise.
For the inner Cylinder
The only part not designed is the inner tube that holds the star so what i did is to use a siringe tube, filled it with transparent silicone (the one used to seal windows and such) halfway, put the star in there and then
fill it the rest of the way up.
Then you cut the extra plastic off the tube so its a flush cilinder and glue (or preferably epoxy) the top and
The rest of the parts you just print and put together.
