Team Associated B7 Ball Diff Cover

Team Associated decided to change the B7 to use bigger outdrives however didnt bother to make the little dust cap any bigger so it usually just falls out or atleast doesnt work as intended by keeping any dust out.

I designed this to fit properly. Print tested in both PETG and TPU, its a good solid fit for me and should do a better job of keeping dust out of the thrust drive, which will hopefully allow longer run time.
