In the library on Up Studio, i got a design. however i would like to make some adjustments, as it is an up3 file is their a way i can adjust it? I know i can edit it if it was an STL file but is this possible?

Thanks in advanced

I've looked into it. From what I can tell, the up3 is a wrapper/encrypted compression for an stl , sort of like a RAR file, but a proprietary format.

Open it in notepad and you see 'RP Solids -- CSM3.0 Compressed data' - but for the life of me, I can't find anything to work with it. You can't even export it from UPstudio as an STL or 3MF model.

I've tried a few different pieces of software, from 3d Builder to Fusion 360 and Maya. Nothing 'free' opens it as far as I can tell.

You could have a look at some of the stuff that was being done with the original upbox here - https://github.com/UP3D-gcode/UP3D

users developed a method to intercept the USB data and convert it to gcode - if you can reimport the gcode and convert it to a model you might be able to get somewhere.
