Xbox controller holder, a solid version of the veroni design I first uploaded due to request.
Remove the brim
This model is designed to be good to go, remove the brim and all should be well.
A lot of program swapping
I found a base model of a controller on grab-cad and then modelled a surface offset from the back of it. from there, there was a lot of program swapping between different CAD packages at uni to get the surface suitable for printing and adding in the back support.
I haven't actually printed this model, I printed the veroni design model and have made this solid version available due to request.
