Shirdal P4 V2 (Nerf Gryphon Remix)

Introducing the Shirdal P4 (poor person's pew-pew) V2, a gryphon remix that adds a neutron solenoid back-end and battery containing grip to the gryphon ecosystem.

Demo video here: 

Features include...

Three-way select fire using functions from Airzone's Narfduino library and circuit designed by Dan of 404 designs

The battery is housed in the grip, sized for a 950 MaH OoD 3S, and held in place by a rotating cap and thumbscrew on the bottom of the grip.

Dual-stage trigger: Trigger micro-switch is full-sized for good tactile response (Gotta get them big clicks). 
Rev switch is a cherry style; there is enough internal space to wire a mini mosfet board if so desired.

Full gryphon magwell and cage compatibility. The noid should have enough throw to use everything up to and including banned wheels. Two versions of each side panel exist for pre or post gryphon version 1.3 magwells.

Magwell designed by Taffy: The included magwell was designed by Taffy for use in his personal gryphon and let me tell ya, it's buttery.

Holdster support: Holdster mounting points have options for both left and right hand holdstering.

Stock support: PVC stocks, buffer-tubes (using imperial and metric pvc cores), n-strike, and a stockless voltmeter display are all included to make carbine or pistol variants.

eclectic notes

•  The compact rail is made for use with my compact pulsar/banshee Jr's cages. Get those here. 
• The rails here are meant to be used with the taffy magwell and shirdal body panels since the middle two screw holes will not line up with standard gryphon holes. If you just want to use the gryphon cage, use the appropriate rails from here.
• If the screw holes are tight, I find widening them with a 3/32 drill bit to work pretty well. 
• Two pusher versions are supplied, one is meant to be used with a 2mm thick o-ring while the other is not. The O-ring provides cushioning to quiet the noid a bit but over time the o-ring will fall apart and have to be cleaned out. Regardless, use super glue to when threading the pusher on.
• The microcontroller can placed inside the grip if using a battery stock or behind the solenoid in the angled slots on the body panels. The small hole in the body top panel allows you to stick a usb cord into the microcontroller without having to disassemble the whole blaster. 
• The imperial and metric buffer tube stocks refer to whether or not you should use 25mm or ¾ pvc tube as the inner core of the stock.
• The taffy magwell uses the pre V1.3 grpyhon grip-magwell interface. Download the appropriate grip-core if using that.
• If you're looking for a non-solenoid version of the grip, grab the parts from gargunkle's remix here or use my own version. 

update 8-16-2023: Just realized the side and top panels were based exclusively off of taffy's magwell, which is a variation the pre-1.3 gryphon magwell. I added additional body panels that are compatible with post version 1.3 magwells.

update 7-22-2023: Added support for medium sized holdster fids for all panel types. Redid battery cap, gripcore, and grip scales to make the battery cap hinge around the grip core, giving it greater rotational range.

M3*6 mm screws: For solenoid mounting to body panels

M3* (6,8,12) mm: All body screws are M3. 6 mm are for grip scales and flash hider, 8mm can be used basically anywhere else. 12mm is for the screw that goes through the mag-release and stock mounting holes.

If using holdster magnets, you will need two M5 nuts to secure them to a body panel
