Surface Dock 2 Stackable Holder

All the designs I could find online were for a single unit to be wall mounted. I needed a stackable design to reduce space/clutter on a computer provisioning desk.
So here's my attempt at a stackable holder suitable for a Surface Dock 2 and (almost) a Surface Dock 3. As you can see in the picture, the Dock 3 is a little bit wider so it sticks out from the front but it still fits good enough for what I needed.

If you print it with with the back plate facing down, then the legs will require a minor trim of 1/2 layers to make it sit in the stackable holes on the top.
