Please see: 290mm Ball Cup Arm Set
These RostockMAX ball cup injection molded arms feature precise fit without modification! They are designed to work flawlessly with our injection molded carriages. Spring loaded tension eliminates any backlash and also makes assembly a 'snap', literally! The arms are also longer at 290mm to give better reach and resolution out at the extremes of the Rostock's print area. This does decrease overall print height but the increase in print area and strength are well worth the loss of about 1" in height.
You must have the injection molded carriages in order to use these arms. They have the features to attach this item.. If you DON'T have injection molded carriages, you will need them to install these arms. Click HERE to order the injection molded carriages.
