Inlet Cap V1

implemented unverified

Vertical Farm Pack (VF-9.2 chute-cap): the Water Inlet Cap — a support-free Г-hook whose water path is VISIBLE. The drip line seats in a vertical tube socket on a STOP SHOULDER (it cannot be pushed through); a narrower drip orifice drops the water through a short covered chamber into an OPEN-TOP chute (a U-trough) that carries it inboard and drips it off the nose tip onto the rail's floored lip-seat, safely inside the channel (fluid_joint, gravity is the pump; the mounted row tilt drains both the level trough and the rail channel). No closed horizontal water tunnel, no ambiguous through bore (form.cap_water_path_visible); brush-cleanable from above. HOOKS the outboard edge of the rail back wall — a short rest ledge on the wall top, an outboard leg/foot to the bed — and prints AS-MODELED with no saddle_up flip (manufacturing.cap_supportless_verified). Magnets dock on the vertical +Y face. assembly.saddle_hang_ir verifies the hang in the fluid pose. Local frame: y=0 = the rail back face, -Y inboard toward the channel; z=0 = the cap body bottom.

Parameters

parameter	type	default	range	role
`cap_w`cap body width across the corridor	`length`	`64mm`	`40mm … 120mm`	functional	exposed
`cap_h`	`length`	`22mm`	`16mm … 40mm`	structural
`tube_od`outer diameter of the silicone feed tube (hardware, BOM)	`length`	`9mm`	`6mm … 13mm`	assembly	exposed
`bore_clearance`push-in grip over the tube OD	`length`	`0.4mm`	`0.2mm … 0.8mm`	manufacturing
`socket_depth`VF-9.2: tube socket depth to the STOP SHOULDER — the tube seats there and physically cannot be pushed through the cap	`length`	`12mm`	`8mm … 14mm`	functional	exposed
`orifice_d`VF-9.2: the drip orifice below the stop — narrower than the tube (the stop is real) yet wide enough not to clog	`length`	`5mm`	`4mm … 7mm`	functional	exposed
`cassette_w`shared cassette envelope — sizes the rail wall the cap hangs on	`length`	`177mm`	`160mm … 236mm`	assembly
`seat_clearance`	`length`	`0.75mm`	`0.5mm … 1mm`	assembly
`module_w`shared rail module depth — sizes the rail wall	`length`	`205mm`	`200mm … 250mm`	assembly
`seat_depth`shared rail seat depth — positions the handover	`length`	`14mm`	`10mm … 20mm`	assembly
`channel_d`shared rail inlet channel depth — positions the handover	`length`	`5mm`	`4mm … 8mm`	assembly
`channel_w`shared rail channel width the spout dips into	`length`	`16mm`	`12mm … 20mm`	assembly
`spout_w`spout tongue width — must fit INSIDE the rail channel	`length`	`14mm`	`8mm … 18mm`	functional
`saddle_depth`	`length`	`8mm`	`6mm … 12mm`	structural
`saddle_fit`	`length`	`0.4mm`	`0.2mm … 0.8mm`	manufacturing
`corner_r`	`length`	`3mm`	`2mm … 6mm`	aesthetic
`dock_magnets`VF-6: dock the cap arm onto the FIRST rail's back wall-top magnets (rail needs endcap_dock: back) — alignment only. Keep cap_w wide enough that +-dock_x stays inside the arm (64 fits dock_x 22)	`bool`	`False`	`—`	assembly	exposed
`dock_x`dock magnet centers at +-dock_x — must match the rail	`length`	`22mm`	`14mm … 40mm`	assembly
`dock_inset`dock pocket step inboard from the rail face — match the rail	`length`	`7mm`	`4mm … 12mm`	assembly
`dock_fit`diametral press-fit of the d6x2 dock magnet	`length`	`0.2mm`	`0.1mm … 0.3mm`	manufacturing
