Festool router guide bushing adapter

This is a Festool router guide bushing adapter. 

It is designed for a Festool OF 1000 EB, but it should also work for other festool routers.

Thanks to the holes, the dust extraction works very well.

The size I made is for an 8 mm router bit, and the outside diameter is 14 mm (see picture).

Other sizes can be avaible on request. 

I printed mine in PLA + with 100% infill on ender 3 V2. It is sturdy enough, but can flex a little if you push too hard. 

By tweaking the outer ring with masking tape, I was able to ajust the tolerances and route a wooden bowtie inlay (see picture).
