A can of money!  Keep your loose change (Aussie) neat and sorted in this can.  Holds loads and the can fits nicely into a car drink cup holder.  Frees up your ashtray for more important things like...err....buttons, keys, etc. Printed in ABS, 0.2mm with support.  Painful to get the support out - just hard to get in there to get it, so I suggest using very course support.  Might do another version that is curved inside the coin slots to avoid support.
