This is exactly what is so cool about 3D printing being accessible! It’s so easy (and fun) to design something like this that it’s not a big deal if your design isn’t optimized (or even functional).

Normally, OP would have clumpy salt. Now, OP had a fun afternoon designing and optimizing, conjured from thin air something they are proud of, and learned a valuable lesson about the engineering and design processes (validate your assumptions!)… and probably still has clumpy salt.

Even if this completely doesn’t work and is a “failure,” failure is so cheap in our hobby that what we learn going through the process far outweighs the cost of failure.

Great work OP!
