Ok I'll go first. This is one of the many twisted vases on Thingiverse. Printed it more for learning than anything else, but it turned out alright I think.

Hey,
I printed a twisted vase as well today. I designed it myself in openscad for practice (which was actually easier than anticipated), and I ended up printing a much bigger version than I intended, but here's a picture (with a spool for reference). Diameter is 10cm, height 18cm, plastic from ColorFabb, sliced with slic3r's twisted vase setting. I ran slowly so it took 5 hours, and it came out nicely. (The white specs visible in the picture are barely visible in real life, but I think they must be from the plastic).
Here's the openscad code in case anyone's interested in playing with it:
Code: Select all
$fn = 60;
linear_extrude(height=100, twist=60)
circle(r=30, $fn=6);

Ketil, do you use a filament dust cleaner? Such as a cloth and a zip tie or one of these
http://www.thingiverse.com/thing:153807. Possibly there is dust getting in there and causing those spots? I notice when i let my filament sit out a bit it gathers quite a bit of dust.

No, but it's definitely on my todo list!! I don't have anything lint free available right now, and I did actually notice that the roll was a little dusty... So that's probably it.

That model i linked it pretty nice. I just cut up a piece of sponge to use as the collector.

nice! i think the one i printed took about 4.5 hours. do you guys know of a way to get vase mode to print two layers for the wall instead of 1? the walls seem pretty flimsy as is.

I just came across this and thought it amusing. No need to sit through the whole thing, skip to the end of print:

What happens when you neglect to shell a vase print.

You can always modify the OpenSCAD file to specify the actual wall (and a base, too). The original OpenSCAD just defines a solid object, so I guess it's sliced by setting infill density to zero and not printing a top and bottom solid (or maybe the bottom is solid? I haven't printed the part). The following OpenSCAD code shrinks the geometry, shifts it up, and subtracts it from the original. The variable "$thk" is then the thickness, which will be in mm if you don't scale anything in the slicer. A single filament wall is 0.19mm (with a 0.35 nozzle and 1.75mm filament, and subject to calibration-related differences).
Code: Select all
$fn = 60;
$thk = 2;
difference () {
linear_extrude(height=100, twist=60)
circle(r=30, $fn=6);
linear_extrude(height=100 - $thk, twist=60)
circle(r=30 - $thk, $fn=6);
}
