Custom parts and enclosures

Turret body

The turret head holder and head mover servo part will need support to print

Turret head

It contains thin built-in supports, so generate supports at only those parts where it is touching the buildplate and not inside the model. After printing you need to remove these sacrificial walls.

Turret bottom

No supports needed

Trigger solenoid attachment

Contains build-in support. No support needed when printing

Trigger pin

Support needed for the bottom part. This will be attached to the end of the solenoid

Camera holder

No supports needed

Clip connector

Needs supports

Schematics

Circuit diagram of the Airsoft Turret

The 3.3V regulator of the micro:bit expansion board will provide power for the micro:bit when it is operating from battery. The input line of the regulator isn't easily accessible, so I recommend you to solder it directly to the regulator's Vin pin. It is also accessible on a side port of the expansion board, but that has a different size. The micro:bit also have a 5V pad, but that also requires soldering.
