This is Minecraft Sword I build on my minecraft server it's really simple you make pixel art, then select the area with world edit, save the area with world guard, stand in the region and type /print. I used a plugin called "Print Craft" and can be found in the Thingiverse - Explore - Apps Section and will find the printcraft website and from there you can find the plugin, you will have to have a minecraft server and will have to be running bukkit or spigot and can follow the steps above. If you can't host a server, you can come onto mine and can build (Msg for the ip skype name: girmane514), and i will get the website URL and give it to you so you can print your builds. On the printcraft website screen where you have your build, you have multiple things you can click for like the STL file or share on thingiverse ect.
