Tensioner / slider for flexible slat bed

While moving our slat bed we discovered that most of the tension adjustment sliders had broken.

While replacements aren't too expensive, it was much faster to just model this up and print out as many as we wanted.

I printed in ABS with high infill, they seem quite tough but we'll see how they last. Possibly something indestructable like nylon might be worthwhile.

OpenSCAD source code lives on github at https://github.com/Lenbok/scad-flexible-slat-slider if you want to adjust for different width or thickness slats. The current model is for slats 9mm thick x 53mm wide.
