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.
I’m not entirely sure I understand your problem.
So i filled the hole like you, but left the gap. I also deleted the faces inside so that it remained a solid. However this is a waste of plastic and probably better to redesign. But hopefully this can get you in the right direction. Bike-piece.skp (565.3 KB)
