Here is the design for the avionics bay sled. The main portion of it is currently printing.
The rocket will feature two completely independent sets of dual deploy electronics for full redundancy. The primary altimeter will be a MissileWorks RRC3. The secondary altimeter will either be a MissileWorks RRC2+ or an Altus Metrum EasyMini (the sled is designed so that either one can be used). All deployment charges will be shunted prior to arming the altimeters on the launch pad by means of two pull-pins. Each pull-pin will simultaneously control three Omron SS-5GL switches (I'm using the triple pull pin switch kits from Lab Rat Rocketry): two responsible for shunting the main and drogue charges and one to turn on the altimeter. The shunting switches will be wired in such a way that continuity across a deployment channel will not be detected by the altimeter if a charge were to somehow remain shunted. Planned wiring diagram shown below:
