So here’s a quick video of the first try at an impeller. I haven’t found much info on materials that are suitable to being soaked in denatured alcohol or other solvents for long periods, but I’m open to any suggestions. I have never done resin casting, but would be open to trying that that if there was something that can take being submerged in all the various cleaning options for resin.
The problem of the magnets coming out has been solved with the new revision. But I did have problems with the hot filament sticking to the cold neo magnets on that first couple passes over the top of them. I had to watch and kind of press down the plastic that was starting to lift on those layers. I’d suggest heating up the magnets before imbedding them. Just sitting them on the heat bed for a while should suffice.
V2 could still take on the bend from always being coupled. Maybe a simple piece of carboard between the bucket and the base, when not in use, is enough to break the tension and take the pressure off the part. I’m not sure, drop a comment if you have any ideas for a fix. In the meantime v2 is printed with 999 walls, and in the bucket. We’ll see what happens after this one sits for a few weeks.
