Working on scad versions of the tantillus xy ends so that they can be customised to take different bushings from the original printed ones.
This is for the metric tantillus so the holes are sized for metric vitamins.
You can generate both left and right versions of the x_y ends using this scad and dxf.
Now printing one to match against the original but if you use 4 of these then they should work.
To create the part in OpenSCAD you need the dxf and either one of the scad files.
The scad file with frp creates a tubular path for the filament rather than a cuboid.
