I remade this Virtual Wall base from scratch, without STEP file in October ‘23 but forgot to post the model.
It's mostly based on that model, except the base is smaller and the walls of the VW insert is higher.
The VW fits like a glove (if your printer has been calibrated right!).
Pro tip!
Slice a piece of the top and print that first just to ensure it fits.
I've also attached the step file to this model page so you can adjust it in any way you want.
The author marked this model as their own original creation.
