LTT Backpack Gridfinity Base

A simple Gridfinity baseplate sized for the LTT Backpack. I didn't find anyone else having made one, so I decided to give it a try.

I first tried various Gridfinity generators, with the idea of then using that as a base, and enforcing it a bit. Then I found that a Gridfinity Workbench existed for FreeCAD, then the rest was easy.

While I was looking for what anyone else have already made, I stumbled upon the LTT Backpack support by Keroro. While I hadn't really noticed much of a sag/slump with my own backpack, I decided to incorporate the idea into this Gridfinity baseplate as well.

I've quickly created some bins using the Gridfinity Workspace for FreeCAD, so there's something to start out with. I've named them according the number of units used for each axis. They are made with no magnet holes, thin stacking lip and the walls made to 1.9mm so the lip and the walls are the same thickness, which also have the benefint of adding strength.
