This tool can slit (corrugated) pipe. One may want to do slit a pipe for cable-managing where the connectors do not fit through the pipe. The picture shows an older but functioning version. The models are based on an updated improved version.
The odd orientation of the model is for printing without support. I recommend a brim for better bed adhesion though.
Use some M3 screws and nuts to fix the utility knife blade.
I did the model work with OpenSCAD. Future work will be tidy up the code and publish it as well.
The author marked this model as their own original creation.
