CAD Helper Models
thingiverse
When designing a frame, one of the most important things is to have a digital version of the sorts of parts you intend to use to make sure that everything will fit properly. That's why I painstakingly CADed some good helper models to use when designing a frame. If you use Fusion 360, download the .f3d. Otherwise, download the .step. Hope this helps! This page will be updated as I add parts.
