A veritable mini cannon that can fire a small red Technic pin 10-12 feet! This is 100% my own creation, I did not get inspiration or mechanisms from anything or anyone else. Enjoy!
About this creation
How it looks from the back.
The cylinder needs to be rotated by hand every shot, and you cant tip it backward or else the bullets fall out. Unfortunately due to the compactness of the design it is not possible to counteract this. (If you know a way, let me know in the comments!)
The left side of the gun. Not very interesting...
The Mini Marauder fires 6 small red Techinic pins.
Spare ammunition case.
Spare ammunition case, ready to reload!
Spare ammo case partially taken apart.
All of the pieces for the spare ammunition case.
The third wheel-thingy keeps the bullets from falling out.
ADS (Aiming Down Sights)
The firing mechanism uncocked. It isn't that complicated of a design, and if you want to use it, feel free, just give me credit!
Fully cocked and ready to fire!
The firing mechanism at half-cock.
A close up of the gear mechanism on the outside. The third gear is necessary because otherwise the trigger mechanism could not prevent the hammer from firing the bullet.
Looking down the barrel. Potentially the last thing you will see! (At least in one eye.)
The instructions are mainly accurate, but with a few improvements I wanted to make but couldn't due to not enough pieces, along with a color scheme I liked. Also, in the LDD instructions the piece on the inside end of the trigger is a 1/2 bush, but I used a 1/2 bush with gears (which isn't in LDD) and it works MUCH better.
