This is a coveliding door for the upper cavity on the coole arm rest hinged top on a Tesla Model 3. It tur a somewhat strange and not very useful cavity in the arm rest into an unobtrusive storage area. There is a commercial product that performs the same function but I figured I could easily make one. This is not a copy, just my take on how to do something similar. This project is very simple. Printed parts are 4 flat pieces and two uncomplicated side pieces. All you need to itall are (6) M3 x 10-ish screws and some 3M Command double-sided tape strips. Edit 1/8/2020: Added slide and door stl's sized for putting vinyl wrap on the surface. Fit pictures now show the vinyl wrapped veio. It looks much better. Wrap is Vvivid matte black: This wrap comes close to matching the color and texture of the coole plastic. You might notice that the cover sits proud at the bottom and recessed at the top. I did not see that the cavity is deeper at the top until italling the frames. I might redo this and taper the frame depth so the slides sit uniformly at the surface. But for now it looks great and works so not a priority.
