Assembly

Once all parts have been been printed, assembly is fairly easy requiring no external tools or supplies.

Internals:

Take the Gear Connector bottom and insert in to the Gear System Bottom (The ring system which has no holes for stacking) as shown below, making sure that the pegs are inserted into the smaller gear holes. 

Now take one of the Middle Gear Connectors and stack onto the Gear System Bottom as shown below, it should slot onto the outward facing peg easily. Afterwards take the Gear System Middle and  connect it onto, aligning the pegs with the given holes.

Repeat for the last Gear system. It should look this this below once done.

Once the internals are assembled, take the entire Gear System and slide it all the way into the Middle Casing

Take the Casing Bottom and attach it the bottom peg of the Gear Connector Bottom that is sticking out of the bottom of the main body, connect the Casing Top to the pegs sticking out of the Casing Middle, and connect the Vial Holder to the Gear System Top outwards peg
