I am a newbie to 3d printing and to sketchup and I am trying to modify an stl from thingiverse. This is the thing http://www.thingiverse.com/thing:779012
What I want to do is to modify the modify the end that is supposed to go around the bike handlebars to be flat so I can sandwich a strap in there instead.
The closest I have come is to fill the hole with a cylinder and cut it but I haven’t been able to get that to work completely.
If anyone could point me in the right direction it would be great.
