model breaking away from supports

Hi All,

Trying to print this odd shape which needs supports, but have problem that around halfway thru the print, the model breaks away from the supports.  Have played with the support settings a bit, but cant find a way of getting the supports closer to the model - or with more links to make it more robust.  Any suggestions welcome here is 3mf file: Constwidthshapes

It is inherent in the geometry of the shape(s) - in fact it's the whole point of these shapes - that as any turning force is applied there is no increase in the force applied to the support so nothing to resist breakout.

I suggest splitting the part and printing both sections cut side down before reassembling after printing.

Cheerio,

Thanks for the suggestions.  I did not find a 'snug' setting in the slicer, but I will try the 'organic' one.

Meantime I will also try printing the part 'upside down' - so on the large flattish area.  Think this may work - it provides much more contact surface beween the bed and the part.

I take the point about the part being a constant width, will think about cutting in two and joining afterwards, but its not a preferred option.

Printing the part 'upside down' ie with the flattish surface down, and supports right out to the edges ( ie > 70 deg angle ) works fine.  Does mean a bit of cleaning up on that face, but a few minutes with a bit of sandpaper works.
