You can place a Personal Marketplace at your base. This will allow you to buy items from vending machines around the map, just like the marketplaces at Bandit and Outpost. I recommend you place a 2×3 platform for it to go on. You must have building privilege to place it. Gather the components to build it, issue the command and place it. It will look like a wooden box before your place it.
Command to craft the personal marketplace: /marketplace.craft When used, it will tell you what components you still need.
The marketplace can be picked up with the /marketplace.pickup command or by using a wooden hammer.
