[member=80962]Jaytool[/member] instead kludging an adapter together, just replace the tool end on the Bosch hose with a Festool 36mm tool end. The Bosch hose is 35 mm it will fit fine. There are threads here on how to replace the hose ends. But fairly straight forward.
The tool end will then fit over the tool dust port.
What I would like to do is replace the saw fitting because I use this hose on other tools.
This is the adapter:
