This 3D Printed router mount adaptor is used to make any router/spindle fit tightly inside the standard Openbuilds router mount. By default the mount is designed to fit the Dewalt D26200 or Bosch Colt, with a 71mm OD, for any router/spindle apart from these, a router adaptor may be needed. Standard options are available to fit popular router/spindles, for an extra fee we can make a customised router mount adaptor.
