Snapmaker U1 toolbox and spare nozzle

This is a remix of the model from danivbel. A big thank you for sharing the source CAD as it allowed this remix. I've shared my step file for others.

The remix add space for the spare nozzle you receive as well as some quality of life changes. You can reuse the small screws to fix the tool tidy to the printer. I have also added a cutout to help get the spatula out of the tidy. 

The print profile is in PETG with a PLA support interface. PETG will resist heat better. 

EDIT: Height reduced by 2mm. This is in response from the feedback people have given.
