Thanks guys... they're a handy tool whether bought or hacked out of timber/metal... this is just to highlight how easy and quick they are on a 3D printer... and accurate.
The angles(s) are easy to create... but usually confined to owners of a 3D printer (or contacts).
For workshop jigs/supplements they are invaluable... just think dust extractionm connections... why are different bads, different 2 1/2" diameters... they never "cross pollinate"..
If your first cut is too short... Take the second cut from the longer end... LBD
