Delta Star Drive System

Spectra fishing line on openbeam drive system for the Delta Star 3d Printer. This send the fishing line directly into the groove of the openbeam for attachment to printed sliders. 623vv bearings act as pulleys with a pair at the top of the beam guiding each end into a groove and a single bearing at the bottom to loop it back up. Spool is paired with an additional 623vv bearing on the rail to provide an unwound friction drive system to maintain a constant tension for a fixed length fishing line.
