Modular, highly scalable sliders for squared rods or tubes. By changing one single parameter (profile width) you can adapt this slider to any squared rod size you find.
Even if the rod has some holes in its surface this slider will work.
No support needed for any file. This has been printed successfully on a Prusa I3 clone.
For adapting the design to your squared rod or tube dimensions open
slider23_5_constants.scad in Openscad
into the value of your meassured profle length
Save the file and open one of the other openscad files you need.
Set drucken=1; for compiling by
pressing F6. After that you can export the stl file by pressing the stl icon in the editor window.
For adapting the design you need a copy of the open source software Openscad from
and these additional libraries, otherwise you'll get a compiler error in Openscad.
