Did a quick hack in OpenScad and made the Extender modification parametric. All tough I can use it, it's *not* foolproof.
I created extenders with 50,60,70,80 and 90 mm length. Length is the overall length of the extender, not the extending length.
Lower values don't work (40mm for ex.) and do not make sense also, larger values should but I didn't test.
The zproj holds the 5 variations, you can create your own sizes by just modifying the length in the OpenScad script and set the correct filespec of the original extender on your harddisk.
Update: I am not allowed to Upload .zproj and .scad (Zortrax professional WebAdmins might suspect them to contain dangerous viruses probably...).
I uploaded the .STL files and OpenScad script follows:
--- copy below ---
extension_size=70;
holder_filename = "/filespec of Original BS_Holder.stl";
difference() {
union() {
import(holder_filename);
// 65
translate([0,extension_size-25,0])
import(holder_filename);
translate([0,extension_size,0])
rotate([0,0,180])
import(holder_filename);
}
translate([-10,0,0])
cube([20,extension_size-25,20]);
// 77
translate([-10,extension_size-13,-1])
cube([20,65,20]);
translate([-10,-25,10])
cube([20,15,20]);
translate([-10,-30,-1])
cube([20,15,20]);
}
translate([-8,0,0])
difference() {
cube([16,extension_size-25,4.5]);
translate([5.5,0,0])
cube([5,extension_size-25,4.5]);
}
