3D printing is still very expensive. I asked a lute body to be printed with ABS and cost was more than 3000 dollars , an EOS body costs 500 dollars without any part , an rubik puzzle costs 140 or more dollars.

I am GM Fanuc operator and cost at cnc machines depends on time wasted on cutting the part. If you design your part with solidworks , generate the cutting code and buy a big chunck of cnc machines plastic block , cutting is still cheaper than printing , especially parts are mid or bigger size.
