WARNING: this is the instructions to build a real firearm. It is a blueprint to arm yourself for womens rights, to stand up and fight. And get what is your right. 

PRINT
Layout your elements depending on your printer and printboard size.
The springs must be printed flat on their side.  
The hammer body should be printed such that the firing pin hole is in the z axis.
The hammer should be printed on its side.
The trigger must be printed on its side.
The spring connecting rod bushing should be printed up in the z axis, to reduce friction.
The spring connecting rod should be printed on its side.
All pins should be printed on their side to take advantage of intralayer strength.

PREPARING FOR MOUNTING
All elements need to be sanded and filed for fitting. Depending on printer and plastic, this might take some time.

MOUNTING
Mount the trigger first.  Take the trigger spring and note that there's a very small lip on one side of the ovular hole.  This lip mounts flush to the trigger piece, and gives the spring enough clearance to not drag on the bottom of the inside of the frame.  The spring's free ends should point away from the trigger, towards the back of the gun.  Mate these two pieces, and then insert into the frame.

Next, we'll build the hammer subassembly.  Insert the hammer into the hammer body with the striking cylinder facing the front of the frame.  Insert the hammer pin to connect the hammer to the hammer body.  Now press both coil springs onto the hammer body.  When the hammer is cocked, the coil spring diameter should reduce (not expand).  Once both coils are pressed on, pull one of the coil eyelets behind the hammer, and then insert the spring connecting rod into said eyelet.  Rest the rod on the hammer.  Slide the spring connecting rod bushing over the spring connecting rod, then pull the other spring back and insert the spring connecting rod into the eyelet.  Pull the hammer back and make sure everything is working well.  Pull the hammer back and drop in the nail and then insert the firing pin bushing concentric to the nail's head.  This keeps the nail from falling out when the hammer is cocked.  Notice that one side of the firing pin bushing is chamfered... that side faces the hammer.

Next, drop the hammer into the frame.  Note that the hammer secures the trigger.  Insert three frame pins to secure the hammer body.

Your S.C.U.M. gun is now ready to go!

Before firing, we recommend heating acetone to boiling and treating the barrel for ~30 seconds to decrease the inner diameter friction, which increases barrel life from 1 round to ~10 rounds.
