v slot extrusion wheel with 608zz bearing tpu (hard)

thingiverse

I'm excited to create my own wheels for V-slot aluminum profiles and develop an open-source mechanism for linear motion. I designed these wheels to fit snugly around 608zz bearings, which makes them slightly larger than usual. However, they work incredibly well when paired with these bearings, so if you're in a similar situation, this is a quick and easy solution. My goal now is to create a smaller version of the wheel for use with PC wheels and a smaller bearing. This initial design serves as a starting point for the most common bearing size, but I'm eager to refine it further. I've found that using hard TPU really makes a difference in terms of grip on the rail, making it easier to fit the bearings into place. Please feel free to remix or modify this design however you see fit – I'd love to hear any feedback or suggestions for improvement. If you find them useful, that's great; if not, that's okay too! I've included the .ini profile for flex that worked for my Prusa printer, which prints each wheel at a rate of about 45 minutes. It's not the fastest print job, but it gets the job done, and that's all that matters for now.
