Cura will tell you the outer dimensions of a part; I don't think (or know) it can provide each feature's dimensions.

Oh really. If I can't edit it normally then I will resort to tinkering in c# .net. I'm a programmer by trade. Albeit not very experienced one but I will give it a go if I have to.

MeashLab works great, it supports all platforms (Mac, Windows, and Linux).

I had a problem with my Z limit switch bracket falling just short of the bottom edge of the z stage.

I'm trying to make the bracket thicker so it's pushed more towards the left.

1) how do I measure the thickness of the bracket in the stl
2) HOw would I make it thicker if it is indeed too thin

It's might to be mounted standing up right.

I want to make it thicker x axis (if it's stood up)
