Parametric Box - SolidWorks

I needed a parametric box for a different project but none of the ones I could find used SolidWorks, except one that really wasn't parametric and didn't seem to work.  This one is truly parametric.  All you need to do is edit the Parametric Box Dimensions.txt file with the dimensions you require, save it, then rebuild the assembly model and it automatically adjusts to your chosen dims.  Few, if any, dimensions are hard coded, they are all related to the TXT file dims.  

Unfortunately after you download this you will have to open each part file, right click on Equations in the Feature Tree, manage equations and re-link to the current location of the Parametric Box Dimensions.txt file.  Click on the … next to the Link to External File check box.  If you know a better way to do this please let me know!  If I find a better way, I'll update the files.

Update 12-29-23: I added a .zip file that I used Pack and Go to create.  It “should” reset the link to the extracted location when you extract it.
