Hey! Please make sure your CAD is an assembly with the PCB included (even just a placeholder rectangle that has the same dimensions as your PCB will work). Your PCB routing looks good, if you want to make it a little bit cleaner you can use the B.Cu layer in kicad to put wires on the back of the board. If you need any help with anything you can ping me in #blueprint. Take a look at submission guidelines to make sure you have everything you need.

Hey! Very nice hackpad but you need an image of the assembled model and a STEP file of assembled model of the hackpad.( you can use grabcad.com/library to get the 3d models of components )
