Bulk-Man 3D is the largest wholesaler of Open Source CNC parts to the world. By having the parts produced ourselves, or sourcing the parts directly from the factory, we eliminate the middle man and in doing so are able to provide the best wholesale price direct to the public! The Bulk-Man 3D QueenBee PRO CNC Machine is a linear rail upgrade based off the very popular Work-Bee CNC Machine. This machine is available as a complete mechanical kit with all parts required for the build, as well as being available as an  Upgrade Kit  for existing Work-Bee CNC machines. By eliminating the middle man we are able to provide the end user with the linear rail machine they want and at the best wholesale price available.
