Chainmail coaster

I was playing with the openscad file and tried changing the chain offset from 0.8 to 0.6 (i.e. the line is now "chain(16,16,0.6)") to give the diagonals a little more clearance and found this did two things:
1) It gave the diagonals more clearance, as expected, so nothing stuck when I pulled it off the print bed.
2) There is now less bias in the way it bends because there is more clearance. It is certainly still there, but not nearly as much as before.

I also printed it at 25x25 size, cuz like, YOLO. I want to at some point in my life 3d print chainmail, and I think this design would work extremely well to that end because of how smooth the surface is.

I did have to run the stl models openscad generated through netfabb every single time because it came out with a ton of screwed up polygons. I don't know enough about openscad to debug it, but it could be cool to do more things with this chainmail, despite its age.

Thanks for sharing this!

I know this has been awhile, so you might not remember much about this piece or even be looking for questions. But I want to print this on my Up mini and it only let's me select layer heights to choose from a limited selection, .25 and .3 being the closest. I did download OpenSCAD and edit the layer height value to .3, thinking this would be the better than .25. OpenSCAD successfully rendered it and I exported the STL. ( Thanks for making something that pushed to learn how to do at least this, Before this, I have only been editing in Tinkercad) . But the UP hangs when it tries to slice my edited version. So just to see what would happen, I printed your original .27 version using .25 layer height. The result won't decouple, as expected, but it's close enough to make me want it even more.

Any advice? I don't understand programming in SCAD at this point, to know if I need to do more than edit the .27 to another value. Thanks for any advise you can give.
