Model includes 0.25" diameter holes for screwing into the wall. It also has a recessed back area sized for 3m command strips, I used the 16 lb package with just 2 so it supports 8 lbs. I printed with a 0.4mm nozzle and 0.2 mm layer height with a 15% infill and print came out great. It's current orientation is how I initially planned to print but changed too printing with the wall side down for a cleaner looking top. The screw holes didn't come out super clean in that orientation so if you plan to use them I would recommend printing in the current orientation the file has it in.
