This is my interpretation of the SPNKr from Halo 3. I completely modeled this myself in Fusion 360. The whole model was designed and is split up to be able to print on my i3MK3S and many of the pieces do not need supports. There are a bunch of spots for metal rods to help align + reinforce the prop to ensure it has a long lifespan.
The main pipes are 2" PVC (~52" length) and there is also a 1/2" PVC (~41.5" length) for the grip. There is a text file included with all of the materials if you are interested in making one.
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.
For more details and images check out the thread I have on the 405th about this.

Warning: This is a large project. I estimate ~300 Hours of print time and 3 KG of filament.
