Scalar Slider Back with Brass Nut

thingiverse

The original part utilizes an Igus lead screw nut, which are apparently impossible to find in the US and if I could locate them I suspect they would be very expensive anyway. So, I remixed the Slider Back to use a brass nut instead. I have also included the OpenSCAD file that I used to remix the part. I recommend using OpenSCAD 2018.11.25 (development release) because for some reason the part does not render correctly in earlier versions. Even in 2018.11.25, the preview will look messed up but the full render will be fine. If your brass nut is a different size than mine, there are parameters at the top of the scad file that you can use to adjust things so your brass nut works. If anything has to be changed, most likely it will be brassNutHoleDistance, which is the distance from the center of the hole to the holes that hold the brass nut to the slider (the four small holes on top). Those are M3 holes, and there is also a parameter to change that as well. When it prints, you will see remnants of the original holes for the Igus, those are harmless. Files: * Slider_Back_v3_T8x1.5.stl -- the original file (with the name translated to english), the OpenSCAD file imports this file. * sliderBackWithBrassNut.scad -- the scad file that does the remix * circle.scad -- a small library used by sliderBackWithBrassNut.scad * sliderBackWithBrassNut.stl -- the remixed file, should already be in the correct orientation for printing, prints fine for me without supports. UPDATE: I finally actually built the printer with this part and the hole lined up perfectly. All appears well. I used 4 M3x10 screws and also used some JB Weld to make sure the brass nut stays secure.
