Here’s a picture of how the clamps are attached to the center assembly:
You can see that the upper clamp is attached with the bolt of one of the bearings in the blue center assembly part. The lower clamp simply goes through an existing hole in the blue part. (It needs quite a long M3 bolt, forgot the exact length but it’s something like 35mm or 40mm. You can also use a bit of M3 threaded rod cut to size with a nut on each side.)
If you attach it on the other side of the router, you may also need to “swap” the clamps. What I called the lower clamp may need to be mounted above the other one.
