How do you like that 4" to 2.5" adaptor? I have to do that and I have been avoiding it.
It’s been working great. I modeled it and printed a couple and have both in use. May need a third one soon.
I worked this one up a while back. (Compare to POWERTEC 70291.)
Also have this model available too:
This one was modeled specifically for a Ryobi table saw (a saw I no longer use). This is perhaps more printable than the one I linked above. This one has the larger radius portion down on the print bed.
