WALL MOUNT N SCALE TRAIN SHELF

I made this from tinkercad, i would like to have a track shelf so my train can go around the room. You can mount it with a screw, or use glue and install an LED in the hole. also can be used for a backdrop viaduct kinda thing. This is my first model with a texture.
Filiment - I used hyper petg from creality, but pla is probably fine.
Resolution- 1.2mm
walls- 2
Infill- 10% gyroid

Would love consturctive comments and tips.
