I've checked again just now. It is even said so on the wiki. hears the link. https://terraria.wiki.gg/Weapon_RackI'm pretty sure weapon racks are on 3DS. It's been a year since i have played it but have you made sure you have made a sawmill? Never mind checked wiki. They probaly can't add it in due to the smalle size of the 3DS screen and it would be to much detail for the screen at one time. But idk.
