I printed a long bracket for either side and a short one for the rear, so the laptop cannot be pushed out the back. It's very stable with just the two sides held.

The "Solid" STLs are the structural parts. The "Flex" STLs are a protective boot, intended to be printed from flexible PLA (or something) to protect the laptop from potential scratches.

I've lined it up under my desk so that the SD slot faces outwards - the thunderbolt, power, and a USB port face the back. Tidy!

With the cables mounted somehow, this could make a handy docking station - that's a project for another time. For now, Hoopus.stl is a hanging cable-tidy thingy.
