Free Metalworking Project Plans: FullMetal Rubber Band Gun (Metal Gear Solid)

Material: Steel or Aluminum
Units: (in)

This is pretty amazing. A Metal Gear Solid fan created a version of Solid Snake’s gun that shoots … Rubber Bands! I wish I could find plans for one of these! I’ve got the plans now! They aren’t exactly step-by-step, but they show details for the critical parts. It should be enough to get you started!

Here’s a video of the gun in action.

Here’s a video of the firing mechanism, and a bit of video showing how the gun was built.

And here are the plans, courtesy of James W. from the HSM forum. Thanks Jim! If anyone else has completed one of these, let me know – I’d love to post your project pictures. Also, if anyone has a more complete set of plans that includes 100% of the pieces, please let me know.

About Tyler

Tyler is a hobby machinist and 3D printing aficionado. He teaches computer programming and web development at Highline College near Seattle. Tyler founded Projects In Metal in 2008 because he was frustrated by the lack of free plans available for hobby machinists.


  1. This is brilliant little machining project, challenging, yet a multipart mechanism that works well.

  2. Downloading the files now Andrey. I will post them to the site when I have a chance. Thanks!

    Any chance you could convert them to an .stl file (in millimeters)? My 3D printer builds files from an .stl file and turnes that into G-code. I'd like to try printing the gun just for fun. I would do it, but I don't have Solidworks installed on my machine. 

  3. I added the STL-files.

  4. Here are the Solidworks files. Andrey, you had trouble uploading them because you compressed them into a .rar format, they need to be .zip to upload here. No biggie. I un-rared and re-zipped.

    I also see you added the .stl files to your site! Awesome! I was trying to find a .sldprt to .stl converter. They exist for Windows (eViewer can do it) but not for the Mac. The Mac version of eViewer won't let you export to an STL file. 

    Woot! Now I can print myself a gun! Awesome. Yorkies beware, your dad is going to be armed and dangerous soon! 

    Yorkies, hell … wife beware! Mwuhaha!

  5. if anyone has the full blueprints would you kindly send me a private message? I'm working on getting my 5th lvl machining title in the military and would love to do this project. thank you.

  6. Hi ElderGoose,

    I edited your post to remove your email (to help prevent spam in your inbox).

    One of our members (Andrey) kindly created Solidworks drawings of the gun. His files can be found on his site. If you complete the gun please share pictures of your finished project with us.

  7. Did anyone ever complete drawings for this rubber band gun? In something other than solidworks format, a PDF or dwg,dxf. 

    I plan on building one and it would help with lass trial and error of the parts, thanks


    i can create the CAD drawings and plan on dimensioning in English the 2 page PDF file that is posted, but it looks like it’s missing a few parts.

  8. That is excellent ! Thank you.
