Assembly:
To assemble the dropsetting pin:

Step 1: Test to see if the pusher fits freely into the housing

Step 2: Align the square holes on the pusher with the guiderails of the house

Step 3: Glue pegs to the pusher

Step 4: Aquire and insert spring (I made my springs by heating up some 2.85mm filament and wrapped it around a metal bar)

Step 5: Insert metal pin into front hole (I threaded my pin and hole, but you could probably also just heat up the metal pin and melt it in place)

Step 6: Mount arm on the two pertruding pegs on the house
