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.

Fingers crossed. Seems to be printing fine. Shiny with some stringing. Used Cura generic presets for TPU-95, whatever that is. Higher nozzle temperature (228F) but lower bed temperature (45) than PLA (205/65)

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.

Well finished printing a set of sample things. This comes out looking like the work of a deranged spider like in LOTR. Doesn’t have to. I’ve seen videos of clean TPU prints. Just have to figure out settings.
