Notice: Make sure to design your guns with the handle on the left and the shooty end on the right (while looking at the buttons of the designer).

What? Come on man, you've never hear of Star Tech? Fine, I'll explain it to you. It's a mod that I made for Modjam, loosely based on Guardians of the Galaxy 2. It lets you design and 3d print space guns.

The first thing you're going to want to do in it is craft the blueprint creator

Once you've done that, go ahead and place it down. You'll see a hologram pop up above it, as well as several white buttons, arranged in a line. You can right click the hologram to place blocks, and left click to erase them.

You can edit a button by right clicking it. This will allow you to change the color and functionality of the materials that you are using to create your gun. You can have a good balance of each function, or lean towards a certain element to specialize the gun. Keep in mind that at least 1/4 of the gun must be made from a structure material.

Once you've made a design that you like (Note: Your gun should always face the right, like this example. It's important), you can shift + right click the hologram to get a blueprint.

Once you have the blueprint, it's time to use the printer. This is how you craft it.

Once you've made it, place it down (preferably next to a redstone source) and right click it with the blueprint.

This places your blueprint in the printer. If you haven't powered the printer with redstone yet, do so now.

Once the blueprint is in and the printer is powered, it will start printing your gun! Depending on the size of the gun, this can be a long process, so you may want to do other things. Once your gun is complete, the printer will stop printing, and you can right click on it to retrieve your gun! (You can also shift + right click if you want your blueprint back)

Your space gun works well for killing all sorts of things.

You can even dual wield them!

After a while, you may see that some of the ammo voxels on your gun aren't bright anymore. Their durability bar might also be going down. Both of these are indicators of your ammo level.

When all of your ammo voxels are dead, the gun is too, and you should make a new one! This time, try using different ratios of functions to get different effects!

Effects:

Fire Rate: Affects how quickly the gun fires.
Ammo: Affects the total amount of ammo the gun has available.

Damage: Increases the maximum damage, and the amount of ammo used per shot
Structure: Just for show, at least 1/4 of your gun needs to be made out of this.

Experiment with different combinations to make the space gun that you like best! But be careful, sometimes your printer might overheat....

Other:

You may notice some other features in the mod, namely the infinity stuff.
