Funny last minute gift to give away banknotes, coupons, seeds, letters…
i've printed both parts in in PLA
and paintet it afterwards
a mixture of sand an glue can be applied between cactus an Pot for a higher level of realism
Shiny inner part for the wow effect
there are some artifacts, which you can't see from the outside at the cactus part,
I used windows 3D Builder and was too lazy for corrections :-)
print the inner part at 99,5% in x and y direction (z=100%)
otherwise it is probably to tight
