Actually I misspoke when I said the ender 3 has design flaws. All of its
flaws are in the execution of manufacturing, not in the design itself.
Replace the extruder with an all-metal one instead of plastic (the
plastic one cracked in a few weeks for me, so filament slippage) - cost
is about $15. Drop in a borosilicate glass bed, so you can get better
adhesion than the stock pad, easier removal, as well as more flexible
choice of filament materials - that's about $20. Replace the z-axis rod
coupler with one that actually doesn't slip - cost about $5. And while
not necessary, it makes it a lot easier to get good parts if you add an
automatic bed leveler - $70 (for the th3d one).
THAT is useful information.
One that I saw had a [3D printed] bracket for dial indicator added on for
setting height.
