Something is unclear to me: why set an angle of 19,471??
Seems to me a workaround, if I set an angle of 20° degrees (which should be the correct one) then the sides would not be all equal to each other, nor the angles they make… not a correct Tetrahedron would come out. But if is so, how this workaround of 19,471° was determined? In short, I can’t understand if this is a problem in the Shapr3d Extrude tool, a specific quirk of a Tetrahedron shape drawn in Shapr or else…?
