Stay tuned... 3d printing both rn, and will have a video presently.

I actually don't know if this is the "only" correct answer. Afaict, a 3-projection view completely determines a solid model, but maybe complex surfaces have indeterminacy. I think I'll have to sand off some edges to make it the right answer.

Doh. Of course the solution is not unique. This one is skew symmetric. Any set of contours that fits within the 3 contours will do. I could have added a halfway loft plane with an ellipse cross section and that would have forced symmetry.

Anything contour that stays within the bounding box defined by square and triangle projection lines will work. Blue is what OnShape generated. Red is what I’d force if I wanted.

Also reprinting the horns from yesterday. Scaled down 50% with raft. Dunno what all that wispy stray fiber is. Too dry? From supports being printed coarse? PLA spool being not as good? Drip during travel?

Done. Messed up a bit tried to make the triangle equilateral and the rectangle a square at the same time. Doh. No way to satisfy this template. If you have a square, triangle will be isosceles.

The horns printed fine but that fuzz is a mess. Not sure it will clean up easy.

After some cleanup. Not much better.

3d printing mavens… any tips for sanding PLA prints down to a smooth finish? @divalbanerjee @h_thoreson @chenoehart

Much excite. Printing TPU for the first time. If it works I’ll be able to design my own tires 🥳😱

Just a simple rubbery washer to start with.

ugh broke thread... continues here

Decent compliance, rather stiff at normal resolution printing with 60% infill. I bet I could get much wider range by messing with infill density. But clearly settings need work. But unlike PETG this feels different enough as a material, it’s worth mastering.
