3d print it? posibaly... but that spark will eat up the plastic... and melt it...
any suggestions?

I can see only four options:
1) either use very little voltage so that the spark is little (but you will not get anywhere with this option)
2) use ceramic comutator (which would be hard to make but i like this option)
3) use hard wood comutator (which would have limited use if you would have big sparks but i think that this one would last much longer then the plastic one from the 3D printer)
4) make let's say 10 plastic commutators from that 3D printer so that the spark is 10 times less like Newman did on the page 292 (this option is not good because if you increase the voltage then you might need more plastic commutators because of the fire, blank, short setup).
That is why he solved it with the capacitor parallel to the coil, you use as much capacitance that is needed to stop the spark from appearing, Page 525.
Anyway, i would go with the third option
