R2-IQ: The Round Head
In SnapCAD (VEX IQ modeling software) I drew up a part that I thought would help.
|Part 1 Printed|
I received a reply from someone I didn't even know with this drawing that looked better than my original one.
"I didn't know the angles, so I used 70 degrees."
As near as I could tell, I wanted them to be about 18 degrees (or 72, depending on the reference) In a very short order, he had a new drawing, and thanks to friends (Davin) at Purdue Polytechnic, I had the new part printed in no time.
|Part 2 Hole|
|Part 2 Hole in CAD|
|Part 1 actual angle|
I'm not sure how to calculate that angle. I'm sure someone can. David did it by lining up all the other parts in CAD and having it tell him the angle.
|P2 Original Curve|
Basically, I asked him to push the point in, while leaving the attachment points in the same place.
|P2 Good Curve|
|Head with Parts|
The curve looks very good.
