Rep Rap main bracket upgrade

https://www.youtube.com/watch?v=P9qoBnejlG8

i found the rep rap main brackets to not be what i liked, so i changed them to what i wanted. these are as wide as a washer for an 8mm bolt and have a boss for the washer to rest against. thus being more sturdy.

this is part of my open source RAPTOR 3D printer.

you will find the build of the printer on my forum, as time allows
