Instructions
1. Print - everything is on one sheet, and fits the Cupcake
2. Glue in the two shortest stubs onto the circuit board clamps
3. Glue in the two slightly bigger stubs onto the head
4. Get some bungie cord and one of those bungie cord locking thingies you find in backpacks
5. Cut some thin sheet metal to hold the bungie cords to the bolts on the joint (see pictures)
6. Assemble everything using M3x12 screws (you will need 6 bolts and nuts)
7. There are 2 attachment adapters for the heads - one with a hollowed square, one with a U shaped channel. Fill them up with some foam to hold different components. These can be attached to the head with velcro.
Additional Notes:
1. For the sheet metal, i just cut up a soft drink can
2. All bolts/nuts should give the joints free play of movement - the bungie/angles provide the forces necessary to hold the circuit board/components - use some Locktite to secure the nuts
3. I usually brush everything with some acetone for strength; especially the clamps
