The file 'String Or Spectra Line Tensioner – Pivot Style 3D Printer Model' is (zip,stl) file type, size is 9.4MB.
Designed to take up the slack in a string or spectra line for a motion system. Uses a pivot style design with a pushing screw, and a capturing draft feature as securement for the extra loop the string goes through to produce tension. All hardware is M3's, I recommend using 2 x M3 x 10mm for the ends and 1 x M3 x 16mm or longer for the pusher.
This design principle for a tensioner can be adapted to belts too. I've attached the source CAD if you are interested in remixing it.
