About this 3D model
This is a replacement for the printrbot base. It will prevent both the Z axis and the Y axis stepper motors from bending outwards. The bending problem is shown in the picture(s) below. There is an alternative version available which integrates a support for attaching the Y-stop switch directly to the base. ** update : uploaded a V2 of the stl with Y-stop. It contained a little error which gave a manifold error while slicing.
