Silly Shell --- 6x Short Darts --- Airtight Barrels (3x2 Short Darts / 18x Foam Balls)

Update (--> for Breacher & Battle Axe)
---------------------------------------------

Silly Shell with 3x airtight Elite barrels

6x Short Darts  /  3x Elite Darts / 18 caliber .50 foam balls

Update 30.9.2025:
Modified Shell, suitable for Breacher and Battle Axe use: 
I added a modified version of this shell  where at least the WORKER(!) Short Darts will no longer have a protrusion.
For that I added a bit of dead space in the bottom section so you can push the darts down a little further.

I added 3 separate airtight Elite barrels to a silly shell for better dart fit 
and no air pressure loss when shooting.

This shell brings a FPS boost and an increase in accuracy and range.

Alternatively, you can use this Silly Shell to fire .50 caliber FOAM balls. 6 of these can be loaded into each barrel, so a total of 18 FOAM balls.

I have also designed a Silly Shell Launcher Attachment that fits the Silly SCAR nut thread for 16mm aluminium barrels (you can also shoot darts through it!)

I've also designed a few other unconventional multi-dart silly shells with separate airtight barrels or spigots:
*   6x / 9x / 12x Short Dart Silly Shell (+Triple Ramrod)
*   4x / 5x MEGA Dart Spigot Silly Shell
*   SNIPER + MEGA XL Spigot Silly Shell

The file is already pre-oriented.

Print settings (the same settings as for the other Silly Shells):
0,2mm layer height
at least 5 walls
20% gyroid infill
at least 7 top and bottom shell layers
wall generator: Arachne
NO supports needed

Sillybutts recommends 100% infill for the first 13mm of the Silly Shells. 

As with all printed barrels, it is always a good idea to sand the inside of the barrels to smooth it out a bit.

Thanks to Sillybutts for the files that I could use for this remix.
