Printing with PBT and PETG

I just startes to print this beauty. all the white is printed in PETG, like the most of the MTU will be. But every gear component will be printed in som called PBT+ tough. It is very temperature and abrasive resistant. Relativly soft like nylon which wil make these gears run silent and for ever. PBT is about 2-2.5 times more expensive than PLA, but I think it is worth going the extra mile
