After I modeled the Halo 3 Spike Grenade I decided to challenge myself and model a prop that would push me as a modeler. (I have also always loved big guns) After some thought I decided that making the Halo 3 SPNKr would be fun!

After a handful of nights (and some other random times) I present the finished model:
(and yes I learned a ton from TurboCharizard and stole a bunch of his ways of making a model thread)

The model is 100% designed (and split up) for easy 3D printing) Additionally, there are a bunch of spots for metal rods to help align + reinforce the prop to ensure it has a long lifespan.

The whole model is sliced up to be able to print on my Prusa (21x21x25 build volume). I also include STLs of some of the larger pieces that are not broken down if you want to work with them in that way. (They are in a folder labeled "Not Sliced")

Files that end with x# are to indicate the number of those items that you need to print.

(And yes - I have one fully printed and will slowly be finishing it)

(One SPNKr - Some Assembly Required)

Please respect the Creative Commons licensing stamped inside, I designed these files for the 405th folks to have fun with and make cool things.

Let me know if you have any questions or run into any issues working with the model!

(Edit - Please share pictures / updates if you do decide to make one. I love to see them)
