Step 1: Remove the outer cover
This whole thing just snaps together and will just as easily unsnap to come apart.
Pry the outer case away from the inner carrier and it will pop off.
Once free, the inner carrier easily slides out.
Step 2: Open the inner carrier
First, pop off the mouthpiece.
Then work your way around the edge to free the 3 snaps. Finally, there are 2 more snaps under the mouthpiece and the top will pop right off.
Step 3: Examining the inside.
These rolls slide easily off their capstans.
Step 4: In to the gears
It has a counter to let you know how many of the 60 doses remain and clutches so if you fail to fully cock it, the next attempt completes the action instead of wasting a dose.
Now all I need to do is figure out what to build into it.
