RIB Gusset Options: Base and Tines

[aloarjr810]

I was wondering if the RIBs could have a option to add a base and/or Tines.
A base can increase stability plus allow for thinner ribs, Tines would allow cleaner removals and stability.

ever since I saw the triangle gussets, I've tried to think of a way to slow thelicer trees down. I think adding something like this will keep the forest intact and save a lot of wasted filament. Good idea IMHO.

Thanks @aloarjr810, good idea! A base under the rib is easy to add: a thin, wider plate below it, so it stands better and the rib itself can be thinner. Could you say a bit more about the tines – do you mean comb-like teeth at the bottom that break off cleanly, like on supports? A sketch or a photo would help.

The foot is in now: switch on Foot in the rib's settings and set Foot width and Foot thickness. It starts three times as wide as the rib and 0.8 mm thick, and it works for the straight rib with every top and for the gusset, where it lies under the leg along the floor. You can try it in my demo: https://marcus040473.github.io/?editor=1, and it goes to henmedia as a pull request.

@aloarjr810 for the tines I'm still curious what you have in mind; a sketch would help.

Okay the base looks okay, preferably it should be a ellipse or have the option to make it one or have rounded corners.
You should watch Slant 3D'ss video : "How to Design Better Support Fins for 3D Printing" He explains them and base in detail and why they are that way.

@aloarjr810 thanks for the close-up and the notes on the tines, that makes it much clearer. The rib is @marcus040473's part and his foot is already on the way as a pull request. @marcus040473, could you have a look at the rounded foot and the tines too?

If you'd like to help layerling grow, a small donation is always welcome.

In regards to the "Foot" being a ellipse/round, It helps prevent warping. A 90deg, corner is a stress concentration point, when the plastic cools it shrinks. the stress focuses on that corner. Which can cause it to pull up off the bed.

Curves make for a more cleaner, continuous extrusion for the first layer. By reducing rapid decelerations, jerky movements, vibrations etc. and having a more consistent velocity

@aloarjr810 thanks, that's a good reason for round corners on the foot. @marcus040473 could you have a look at a rounded or elliptical foot?

@dlguess @aloarjr810 the foot under the rib is in layerling 1.144.0 now, thanks to @marcus040473: switch on Foot in the rib's settings and set Foot width and Foot thickness. On a gusset the foot lies under the leg along the floor.

Foot Settings? Don’t see that that I’m aware of at the moment.  Sent from Yahoo Mail for iPhone On Thursday, November 5, 2026, 8:15 AM, marcus040473 ***@***.***> wrote: The foot is in now: switch on Foot in the rib's settings and set Foot width and Foot thickness.

@dlguess the foot isn't in layerling yet. It's part of @marcus040473's pull request, so for now you can only try it in his demo: https://marcus040473.github.io/?editor=1

Ok, that adds a bit more support to to but overall, I think this is a great tree support killer. thanks On Thursday, November 5, 2026 at 09:01:17 AM CST, Stefan ***@***.***> wrote: @dlguess the foot isn't in layerling yet.

@aloarjr810 @henmedia thanks for the point about the square corners. That is where the first layer lifts first while the plastic shrinks as it cools.

The rounded foot is done. Under Foot in the rib's settings there is now Foot shape, with Square (as before, the default) or Oval. The oval foot is an ellipse seen from above, centred under the rib, as wide as Foot width. It is just long enough that at the rib's two ends it is still twice as wide as the rib, so the ends stand on it too. On a gusset it is half an ellipse, flat against the wall and reaching past the tip. The rib keeps its length; the shape gets longer by what the foot reaches past the ends.

It is in my demo first, to try: https://marcus040473.github.io/?editor=1

Grey the square foot, blue the oval one, for a straight rib and a gusset. @henmedia the pull request is ready whenever you want it in layerling.

@marcus040473, thanks, the oval foot answers the point about the corners.

[henmedia]

@aloarjr810 @dlguess this is out now in layerling 1.146.0: under Foot in the rib's settings, Foot shape can be Oval, with no corners for the first layer to lift at.
