Having the motors being the widest parts make then easy to hit. If you want an easy angle gear box get an Harbor Freight 18V angle drill. You then sub in a first motor of the same size, remove the chuck, and then trim or replace the housing.. We used for a grabber a few years ago when 3 days before shipping we decided that what we had could brake off. What we put on did not look nice but it took one day to make and install and it never failed. It was a great gear box. If you look at team 100's bot of a few years ago they had a very nice looking grabber. It also waved to the crowed.
