Gridfinity parametric template

This is a parametric template that I use when designing gridfinity bins and inserts in Fusion 360.  The benefit this offers over the Fusion 360 plugin is the ability to more easily change the size of an existing design, which is helpful when designing similar inserts for similar objects of different sizes or when the object you're designing for isn't a good fit for the grid dimensions you initially expected.  

This model is designed to support both magnet and screw holes on the bottom of the bin/insert.  Screw holes are designed to use a sacrifical layer during printing so that they can be reliably printed without supports.  The thickness of this layer should match your printer's layer thickness.  The sacrificial layer should be punched through with a tool such as an allen wrench after printing.  If you would like to disable the sacrificial layer, set the thickness parameter to zero.  

If you would like to disable the magnet or screw holes, delete the relevant extrude feature.

The top can be made with either a grid or just an outside border with the TopNoRibs timeline group.

This model may also serve as an example for how to use parametrically scalable grid features in Fusion 360.  The key to making this work is setting the object type of your pattern to Features rather than Bodies.
