Printable Linear Bearing and Rail System - Draft 1

thingiverse

This is the first draft of a mostly printable linear bearing and a printable linear rail setup. I make no guarantees to prinability, usability, or sanity. I don't have a 3D printer, so I can't test it myself. If you try it, let me know! If you can't make it work, let me know! I'd like to make this work, so if you'd like to help me, help me help you help me help us all by telling me about it here or on the reprap forums. The non-printable part is the recirculating 6mm balls. Note on where to get them below. Instructions Print one of each .stl file. Note: Something I just foundout. You'll need to scale the .stl files siginificantly. Solidworks exports with the belief that units are in meters for stl files (which is just plain silly). it needs to be scaled by a factor of 10^3, I believe. Assemble bottom-to-top in the most obvious possible manner. Fill with 6mm Airsoft BBs as ball bearings. They're pretty cheap, which is why I designed this to use 6mm balls. Rails are intended to be printed so the triangular indent is down and the traiangular beam is up. There is clearance designed into it so that the overhanging face doesn't need to be flat for two of them to fit together.
