Intentionally designed to look similar to the original MP Select V2 spool holder arm, hold larger (up to 74mm wide) spools, and prints WITHOUT supports.
The 74mm wide spool holder has held every spool that I've purchased. However, the spool holder that came with my other printer is 80mm, and maybe they know something that I don't, so there is also an 80mm long spool holder. Choose one.
I believe that this also fits the Wanhao i3 Duplicator, Cocoon Create, and the Maker Select Plus and Wanhao i3 Duplicator Plus. It just may not look like the original one.
You can use your original nut. I included the nut just in case you need a replacement.
Assemble the arm parts, insert in printer, then secure with nut.
