Is there a way to add support to an existing STL so the support is part of the STL file rather than it being added when sliced, Ive tried to manualy add some support to a file I created but because Ive left even the smallest gap it see's it as a seperate item  :shrug:

Since the following talks about creating supports in Meshmixer, that presumably means they must be attached to the .stl file generated?

I already tried mesh mixer I should of mentioned that  :rolleyes: I'm trying to get it to generate supports in a slot in the side of a box but don't want the supports to come from the bed, I just want it to put some supports in the slot to stop the top sagging down, I was hoping shawdreamer would see the post as I know he did this but forget how he said it was done, I will keep looking  ~~

I have just tried Meshmixer tree support choice for the first time, following the last option in that blog.

I was able to generate tree supports on the rabbit test piece inc ones from the body to the ear, deleting others to bed at will by double clicking them and delete key which took seconds, so ended with a supported pair of ears to the body (its back) and nothing elsewhere.  No time to try printing it but it appears to work OK.

States it allows saving support in file (default) or as separate file.

create a new design in tinkercad.....

import the original stl into tinkercad.....

import the support stl into tinkercad.....

arrange them as you want them printed....

drag select what you want printed....

click "export".....

select "items selected".....

presto, its downloaded as on entire stl and not parts

I tried drawing / creating some support in Tinkercad but the slicer didnt seem to see it and left it out I will have another go see if i can get it to work,
How did you do the built in support for your power bank ?

that was done by simply cutting slices in the box that would be "converted" to a hole and then would be used to cut the hole in the main body for the screen... thus leaving support legs behind when I cut into the main design.

simple method but it works when dealing with simple designs or generally flat surfaces.
