Bosch 1617 Guide Bushing Adapter - Better Visibility

This is a remix of my original version. The original has been working well. I received feedback that it would be better if it did not block the holes in the router base. That way you have a little better visibility of what's happening. It was an easy enough adjustment, So here is the new version.

This is designed for the Bosch 1617 plunge router base and should work for the guide bushings from Harbor Freight..

The screw holes are not actually threaded, but work well with M4 x 10mm screws. Be careful not to strip out the screw hole.

I printed this with 4 walls and 10% gyroid infill. It seems pretty strong for the application.

I'd love to get feedback with other guide bushing brands. I'd like to make this as close to a universal adapter as I can.
