Hello CD
I'm looking for some 80-20 linear bearings or slides. We can't find anything that really pops out at us on McMaster. Ideally, it would only occupy one face of the 80-20. Here's a picture of our small scale prototype slider that we built out FisherTechnic parts and a 3d printed slider.
A little background- this is for my senior engineering project as part of a PLTW course. My partner and I are attempting to design and build an automatic whiteboard eraser.
Thanks-
Adam
