Printing this one out and painting realistically may take a bit of ingenuity.

1) Printed with clear resin (well... as clear as you can make it).
Once printed and cured, add purple resin into the internal part, and cure again!

2) Painted with clear blue + clear gloss coat.

3) Multipurpose filler was used to close up the glass topper and painted over in brown.

The top section is left open when printing, so fill Lickzer with whatever your heart desires.
I trialled mixing in PVA glue with enamel paints and it did NOT work. Would not dry at all over a few days.
