Hi,

Santa brought me a drill tap kit so I started using it successfully on my models. I usually have 3 perimeters but when I cut screws this is getting to thin. Im looking for a reliable way to increase wall thickness only in parts of the model.

Unless you manually edit the gcode it's not going to happen. The slicers as far as I know can only have 1 setting for the entire object.

I could put additional walls in the model surrounding the space i want thicker. It has to be closer than the layerwidth, but then the inside wont be interpreted as the inside anymore and I have to manually support the ceiling which sounds like a lot of work

Perhaps you could just add some very small holes in the model next to where you want it solid.
That would force the slicer to add perimeters there, making it more solid. If the holes are small enough you might not hardly notice them.

Slic3r can apparently do it (I haven't tried it myself): [slic3r.org]

I tap some parts, and I print them with the hole I'm going to tap as part of the model, appropriately sized to be a little smaller to take a thread.

What's the problem with adding a few extra perimeters for the whole part? I do realize it would use more filament and take more time, but the part would be overall stronger and you would be able to reliably tap the hole.

I like Lenbok's find, I never new that was there.
That looks very promising, especially if you've designed the part yourself.

am not sure if this is any use for the discussion but it make an interesting read on modifier meshes with slic3r [www.gyrobot.co.uk] not tried it myself yet so cant say to much about it.

one trick i saw some time ago was to ad very small holes or slots to the print, around the spots where you want more material printed, the slicer would then go around them making that area much denser.
