Small Store for HO Train Set

My first design posted.
- as you see, assembly required building, Pretty tight fit, so take care; because of the close fit, glue may not be needed. I think assembly is pretty intuitive, let me know
- HO scale, roughly 3.5mm = 1 foot, you should be able to scale to what you want to make
- all parts printed flat, so most surfaces are free of layer lines
- open space on the building front for you to add a sign with name, etc
I plan to make several other structures, so i appreciate all feedback on designs or slicer settings. i used cura standard settings with 0.16mm layer height and printed on Ender 3 V2 with hatchbox PLA. have not painted any yet.
