Tardis bookends split into two models

thingiverse

You want to divide the model into two separate STL files, essentially splitting it into distinct parts. This can be achieved by selecting the part of the model you wish to isolate and then using a modeling software or a slicing tool to export that specific section as an individual STL file. The process typically involves isolating the desired component, ensuring its boundaries are clearly defined, and then exporting it as a new STL file.
