Unfortunately, hobbyist 3DP has been all but taken over by the "China-direct" invasion, just as has the "model aviation" hobby. Part & parcel of this is that even with the name brands, one has to practice a higher-than-usual level of

The bottom line is that we pay for our toys in one of two ways: either with our hard-earned $$$ on boutique/turnkey solutions, or by expending our time and patience on parts which typically mostly work but whose QC roughly follows the 80:20 ratio and level of concern expressed in the
Pareto Principle.
