Do you think it is possible to recreate this shape in Shapr3D?  
I just don’t know how to start doing that. Unfortunately I’m not experienced enough yet.  
I have only one left hand so I’m trying to make my own left-handed ergo mouse using other mouse pcb. For now I have only STL of this case.

Looks like in the end I will figure out how to recreate needed shape. Here is the first attempt:

Very nice!  
Are you using **Project** to add edges to the upper part of a curved surface?  
And, if so, are you pushing and pulling those edges with the **Move-Rotate** tool?

If not, then please share how you made those organic curves.

Projection tool doesn’t work with meshes by some reason. So I have to redraw all shapes by hand. I’m using spline tool to recreate profiles in several places and after that using loft tool.

Here is another stage of my work:

It is still far from the end but I’m moving forward.

And all this is still just a proof of concept. I will redraw all after I’ll be sure I know how to accomplish every part.

Nice job using the Loft tool. The only tools that work with meshes are booleans like Subtract, Intersect and Union. You can also Scale with both uniform and non-uniform.  
Here’s what I meant by pushing-pulling projected edges on a curved surface. This video is solely meant to demonstrate the method.

Thanks for sharing. I think that will be useful somewhere too.

Here is what I have for now:
