A generic saddle bracket / u mount bracket that has been setup for parametric customization.

A few notes on the model:

• I included an optional end stop to restrict movement of the thing you are mounting. It disappears if you use an end stop height of 0mm.
• The fillet radius is set as a percentage of the bracket thickness.  I thought this might reduce errors from when you set the thickness to be less than the fillet radius.
• The number of holes in the mounting flange is customizable via a parameter.
