4Z by Molnar 1of2
prototype , only 2 were made
pieces and frame were machined out of 12mm aluminium , with 30mm unit size (it's LARGE!)
to eliminate a shortcut , which would take away the aha moment of the solve .
overall not too difficult , but uses one or two nice moves.
mfg cost were expensive hence the high starting bid ; no more will be made.
