3D printable linear motion carriage with recirculating Delrin/Nylon balls, for use with 60° aluminium extrusion like the Misumi HFS60A5-20. The movement is sitting on the plastic angled plate and the extrusion is held with two little arm on each side, you almost wouldn't need the recirculating balls...The movement is smooth with almost no play. It might be a bit hard to move for some steppers though, the carriage can almost lift a 1200mm extrusion in the air. The extrusion slowly falls down, but sometimes stay up for a bit. The Balls are a bit noisy, but less so with a bit of grease. So your millage may vary... You might need to thinker with things a bit.The "modified recirculating.scad" file will need the original "2020_Recirculating_SideB_BuiltInSupport.stl" file.
