Update (11/12/24): I've made a small change to the standoff on the farthest forward screw to improve how the panel sits on the tube chassis. This change will reduce a twist in the panel in that area that is most visible when looking at the area from above.

I wasn't happy with the fit from other designs, so I started from scratch. The rear lower screw might need to be replaced with an M3x18 coarse pitch screw, but mine fits with the original hardware. If the door panels don't want to fit over the front edge of the rear panels, add a washer under the two rear screws on the doors.

I now have laser cut aluminum and titanium versions of these parts at Freyja's Tiny Trucks.
