should I print fast for the bridges without support or slow? I would say fast because then the connection has less time to drop before the other end is reached....
any hints or tips for that?
I have a UP! mini so less setting tweaks possible...:)

The bridging came out nicely on my Makergear M2. (and I don't have much experience yet so that was on default settings). A bit of wispiness between rungs, but I probably had it on a bit hot.

It's possible with the correct bridging calibration.

don't know why Slic3r made the first layer of every bridge starting from the middle, so from the air...

Perfect! I was hoping I'd find a DNA model to play with, and its even got solidworks sources! I want to make a DNA pendant like the one on thinkgeek, so this will be a great starting place. Thanks!

Print carefully? Print sloooooooowly and as cool as possible, hehe. Leaning tower of DNA much? This will be fun to dial in, I am still working on it

Thanks!
