maybe a little more base

you might not need the complete model but just a little more base to get some lateral stiffness in there. These posts are probably moving a bit when the nozzle travels over the edges...

@swiss_cheese

how would you counter or customize in the slicer for such a model and pla? i don't know what to change since my temp-tower and speed tests were underwhelming and they seem to be the most influential parameters to change for bridges?

Hopefully Helpful Hints

The bridging on this model is easy peasy for a prusa printer, in fact bridging is not the problem here at all. The problem's here are Infill, Heat  and the amount of overhang the few layers before the bridged areas have. this is a small model, the features are smaller yet, a little bit of heat goes a long way, and tiny adjustments to perimeters in the problem areas can make all the difference. sometimes this can be an adjustment to the perimeter widths or a layer height or both, sometimes if we add a perimeter it will remove potentially troublesome infill. it's these tiny things that make a difference to these tiny features.

correct

I let this go enough to watch it hit the bridge.  you are 100% correct here.  the edges start curling up a couple layers before.  By the time it hits the layer where bridge happens, the nozzle is in fact hitting the model.   I'll give your print a try.  I'm quite sure it will be an improvement, you are the filament whisperer after all 🙂

Here is 2.3.3 slice of FOerster's .3mf

swiss you've done it again

Not surprising, but kudos to you for being the filament whisperer 🙂

final result

About as good as I think could be expected without putting some supports in there.

Way to go swiss

Nice print ssill2 I like that color also 👍

These were the results from the .3mf I posted with the adjustments I mentioned previously.

are you a magician?

Not at home for the next days so unfortunately I cannot try your settings right now… but insanely good results, I wonder what your adjustments are? 
And where did you learn these dark arts?

He finds clever ways to make the PrusaSlicer his b*tch lol

That's hilarious, I'm going to take that and set it right here next to my RED NinjaFlex BitchSlap profile.
