For those of us working on building 3D printers or anyone needing parts,
there is a website called matterhackers.com. You will need the .stl files for the parts you need usually obtained from Thingiverse.com.
Email [email protected] and give them the Thingiverse number and the name of .stl files and ask for a quote. The turnaround is just a couple of days and the quality of the printed parts is outstanding! I don't work for them but I figured when a Company does a great job with reasonable prices,
they should be promoted the best we can.
