I modded the original in OpenSCAD
When printing make sure that you :
1) print a copy mirrored (for the other side)
2) go to the original item and print the
...Show more round notched thing for the belt.
Below is the simple openscad script I used to modify the original part.
--------
module belt_cover(){
translate([-40.1,-4.1,-20])
import("C:/temp/belt_anchor.stl");
};
module part_to_remove(){
hull(){
translate([-25.5,8.3,-30])
cylinder(h = 100, r = 26/2);
translate([-28.5,8.3,-30])
cylinder(h = 100, r = 26/2);
};
};
difference(){
belt_cover();
part_to_remove();
};
