Frame for MM-3/3Pro

Pro and Homebrew series Mill Upgrades/Replacements - This is a replacement part for your MM-3 Homebrew Mill, or your MM-3Pro or MM3-2.0.  If you have our older design Pro frames with steel knobs, you can upgrade to the new aluminum knob design with Igus bushings.  The original new aluminum knob design frames were later upgraded with  Igus bushings to stop the aluminum knobs from galling and getting stuck.  Order knobs, and fasteners separately for a complete upgrade kit. For existing customers with 1.5" or 2" diameter roller mill only, NOT for DIY projects.  The older steel knob design 2.0 frames can be modified if you are willing to drill and tap two holes (1/4 - 20 threads) in your existing frames, we offer knobs by themselves and can supply you with a template to show you where to drill so you can upgrade your old Pro frames to the new design.
