This instructable will show how to download, print, and assemble Optimus Primes Laser Rifle. Please note that this instructable is a WORK IN PROGRESS. I am currently assembling my own 3D printer, and it will not be ready for a while. When it is, I will print the Rifle and complete this instructable.

(File on next step)

Step 1: Downlading

Download the .zip file, which contains four .stl files within it. Each individual file contains a number of parts. If you need to scale down some of the parts to fit in your printer, remember that you need to scale all of them. The full size (non scaled) is about 68 cm long.

Step 2: Printing

Please note that many of these parts need to have supports. I tried to separate the pieces that do/don't need supports, but only you know the capabilities and limits of your printer. Because of this, make sure you take a close look at all the parts, to make sure that you print them with supports where needed.

Step 3: Assembling

Since I do not yet have a physical version of this, I will not be able to show, in detail, how to assemble it. I will, however, attach some screenshots and describe as best I can how to assemble it. Once you know how you will put it together, dry fit the pieces to make sure everything fits. You may need to sand/modify some parts to have everything fit together. Once you have done this, bind the pieces together using some type of adhesive (epoxy, superglue...). The handle might be a bit small, so if you think you can make a better one, please do!
