You'll need 5 M3 x 12 socket head cap screws to mount the ramps 1.4 to the mount. Two need to have the heads significantly ground down. I did mine using a drill and a file. Mount the screw in the drill and turn it against the file.
You'll also need 3 M3 x 16 socket head cap screws to mount the mount to the spool holder.
An alternative means of attaching to the spool holder could be done using the spool holder's 8mm threaded rod and a nut or two.
