This is a 3d printed rear motor cover replacement for a number if Bernina sewing machines including the legacy 800 range i.e 801 830 etc and some 700 machines such as the 707 minimatic.
Many of the original covers become cracked or damaged, these play a critical role in separating the motor electronics from the machine chassis. Most of the legacy Bernina’s are double insulated there forever have no earth, therefor it is imperative that this cover is in good condition in order to protect the user from potential electric shock!
