How to upload my works to Thingiverse without making my real name public
To change your displayed name (as opposed to username) in Thingiverse:


Go to your profile page
Click "Edit Profile" on the info column on the left
At the top, next to "Thingiverse Settings" is another link/tab called "Makerbot Settings". Click that.
Change the First Name and Last Name fields, and save.


Note that neither First nor Last Name is required; if neither is provided, your username will be displayed in place of your display name.
