Add support to minimize damage to model
I am trying to add support to this overhang to minimize the damage to the bottom layer, while still providing good support at other places. I find that when support is growing from the model, it really bonds to the model at the base of the support (using PETG).
I've played with first layer density at 50%, style: snug: top z: .3 (this is layer height), bottom Z .1 . no interface layers.. interface pattern spacing at 0.4 ..
Is it possible to support something like this from the build plate by growing the support at an angle? Any other suggestions welcomed.. I could increase the bottom Z but likely it will still bond.. When I printed this model, the top of the overhang was great, but the bottom was a mess.. had to grind quite a bit away.

yes. but there's no button for it.

RE: Add support to minimize damage to model
I have never done anything like this using PrusaSlicer, but I have with Cura, which, in my not so humble opinion, is, in general, more capable with support options than PS.
If someone knows how to do this in PS, please chime in.
Cura has an option to load any arbitrary model as support material. (Within reason, of course.)
I've had fair luck doing a SLIGHT overhang with support material this way. It's tricky and may or may not work in your case.
If I were doing this, I would try drafting a support object that is clear of the main model up to the first horizontal layer and then extends at a 45 degree angle to support the bottom of the next level. I have never done a support structure at such a 45 degree angle but it may work. YMMV. It may be necessary to fiddle around with the support parameters (support density, etc.) to get it to work.
That is the way I would try it, anyway.

You can absolutely do this in PrusaSlicer, but it's an advanced technique though, and depending on the application using the method I've outlined in my other posts is more efficient.
This method is more efficient and you can get better angles on your supports up to 35° as the protractor shows 55° as normal folks say.
and that looks like this.
I have posted several times explaining and with examples, but you still need to understand PrusaSlicer to do this and have a great understanding of supports.
you name it you can support it.
Here's another one I never posted for some butter dish thing some guy needed help with.
I even printed a demo, but there was really no point.
So look around, and if you cant find it after putting some effort in, well the OP has been here for several months now, what do you ask for, to make it easier to help you? it's a rhetorical question.
Good Luck
