A basic template that allow you to create your own omnifixo gridfinity storage solution.  OnShape link: https://cad.onshape.com/documents/8faf36d0265d7c11b8575733/w/f92b2f9ac7b0c90d2896e60b/e/385407b5259cff59fadf6512
 

I have since printed it, and don't recommend it with out some more modifications.  It is a bit to heavy on the side with the metal plate. I think a future exploration will make it a 2x4 gridfinity, with the plate being able to stand up in in the middle, but also have a spot for it to lay over the top if you want to travel with it.  The the plate is 160 x 90, and the 90mm presents an issue because it is JUST to big to lie cleaning over 2 rows. Keep an eye out in the future.
