VTUFF Dust extractor cap

I created this cap for the V-TUF mighty (probaby fits other V-TUF models) as I prefer to transport it without the hose detached and I don't want the dust escaping into the car.I created it dual colour, to try to make it harder to lose.I have included the opendSCAD file, so you can modify it. Note I had to comment out the $fn line at the start otherwise it failed the makerworld file validation (I guess it took too long to process). So to make it smooth and round again simply uncomment. Attached 3mf file uses variable layer height to give nice rounded edges to the cap top.
