This is a simple print to screw the threaded rods on the Anet A8 down to a surface. Dimensions are suitable for use with 4mm screw dia self tapping screws into wood. A flange or dome topped screw is preferable to spread the compression.
WARNING!! - If you have soundproof matting or other soft materials underneath your printer be sure not to over tighten these as doing so will likely pull the threaded rods down and risk fracture of the acrylic frame of your printer.
The design is based on the center of the threaded rod being 23mm from the surface on which it is mounted. If someone specifically requests it I'll post a version which would allow you to customise the distance and the size of the mount to suit different diameter screws and threaded rod.
