Topic: Software to remove parts of a premade STL.

I have a 3D doll that I want to print at 210% scale. The issue is the legs, arms and other parts that have two are made just that way. An STL that contains the right and left. When I scale like the thighs to 210% they exceed my printers 210 by 210 by 300 envelope. So I want to split out just one thigh safe it and then simply mirror it when I want to print the other thigh. Is there any software that does this easily? Like just highlight the half to remove and doing so?

Tinker cad would allow you to put negative object over one leg and then group it essentially removing the part. Then save it as an STL with just one side. They however have an import limit of 25MB and some of these file are over 100MB before scaling.

So any suggestions would be helpful.

Printing since 2009 and still love it!

yeah, Luban would be good for splitting it up - https://www.luban3d.com/

Blender is also quite good at working with existing stl files. I use this a lot

Re: Software to remove parts of a premade STL.

I found that some versions of Cura allow you do to what I need so I am going to give it a try today since it is what I use for the 4Max. Seems to work better on that  machine than S3D.

Re: Software to remove parts of a premade STL.

Meshmixer is perfect for what you want. It can cut the model with a plane or a surface, and you can choose if you want to keep both parts or discard one.

To print or, 3D print, that is the question...

Re: Software to remove parts of a premade STL.

I'm pretty sure the plater in the ancient version of Repetier I'm using allows you to split a multi-object model into separate objects and then move or remove them.

Re: Software to remove parts of a premade STL.

I will look at some of the suggestions. I did find that Cura will do it, but it is very slow even on an i7. I mean it takes about 7 to 10 minutes to create the split file. So I may try something else that is faster.
