HIMARS

Figured I'd take a swing at recreating a HIMARS.  I did my best based on the reference pictures I could find on the internet.  Current scale is only 60 percent of what I envisioned but came out great.  If you elect to print the nerf versions of the rocket tubes you will need to source some small springs for the buttons and then some larger springs for the tubes.  I tested with handyman sp-9705 springs for standard nerf darts in the 6 shot tube (work great but need to cock with a marker or something) and handyman sp-9713 spring with nerf mega xl dart in the single shot tube (this was a little overkill and hard to cock)  Otherwise just print the non nerf version.  It is designed so that you can remove the Crane assembly to swap out your Rocket Tubes then re-assemble and it all holds tightly together. Because of the scale and my lack of print volume I split several pieces into smaller chunks (The frame is split in 3, the launcher is 2, the crane assembly is 3, etc) But I indexed everything so it should fit together nicely just reference the images to determine where pieces are supposed to go.  The Launcher can incline to roughly 45 degrees and it can swivel as well.  All the wheels also spin.  I printed on a FlashForge adventurer 5m because I'm deployed and that's all I have access to, just take into consideration the orientation you print the parts in for maximum strength.  I tried to group the parts together by numbering them so it isn't as hard to figure out how it all fits.  Certain pieces you will need to make copies of to get enough as the STL may only have 1 item in it.  Overall I used just over a spool of filament.  Enjoy!
