I thought the original was a great idea, but when I printed it I realized there was a couple of problems for my setup.
The new version mounts higher on the front rail and widens the display area. I also added a few countersunk mounting holes so it could be screwed to the counter.
There are 2 versions. One moves the holder farther away from the bed so it won't interfere with dust collection.
To mount to the router you'll need M5 x 20mm screws and the appropriate T nuts.
The author remixed this model.
I modified the original to allow to mount higher on the front rail.
