# Wheel Well Garage A full van garage for a 2026 Ford Transit T-250, 148 in wheelbase, high roof, SRW: two Featherbuilt style wheel well cabinets (driver and passenger), a bed platform, a centre bay with a slide out bike tray and drawer, and the storage and utility parts around them. Everything is cut on a CNC router at CCM (VCarve, DXF in inches), with thin plates for the laser and small parts printed in PETG for test fits and PAHT-CF for finals. The single cabinet engine (`src/geo.js`) is unchanged in what it makes: layouts A, B and C, tab and slot, blind tabs or dados with dogbones, nesting and DXF per sheet. The garage engine (`src/garage.js`) builds around it. - **`configurator.html`**: self contained, works offline from a double clicked file (three.js r128 inlined, no CDN, no web fonts). - **3D**: both cabinets in one scene with the van floor, walls, wheel wells, rear door opening and the bed platform. Doors, Tray and Explode sliders, Play, labels and a bed toggle. - **Bay view**: each cabinet seen from the aisle. Drag the placeholders on the mounting panel; collisions turn red and the MPPT clearances show dashed. Auto place puts everything back. - **Sheets**: every sheet, one per material and thickness, with the suggested process. - **Export**: DXF per sheet, garage BOM CSV, garage JSON, PNG, a settings link. Import takes a garage JSON or an old single cabinet JSON (it lands in the cabinet shown in the Bay view). - **`concepts.html`**: the options page the cabinet started from. - **`samples/`**: the "Featherbuilt pair, 36 in bike garage" preset: 11 DXF sheets, the garage BOM and the settings JSON. - **`src/`**: `page.html`, `geo.js`, `garage.js`, `vendor/`, and `build.mjs`, which inlines them into `configurator.html`: `cd wheel_well_cabinet/src && node build.mjs`. ## Show: one cabinet or the garage The Show switch at the top picks Driver cabinet (the default), Passenger or Garage. With one cabinet showing, the 3D view, Bay view, sheets, DXF, BOM, hardware and warnings cover only that cabinet; the bed, tray and van walls drop out and the cabinet gets its own dimensions. ## Your van (the default) Measured on the van, Nov 2026: - Both cabinets 44 in front to back and 28 in tall. The front sits 1.5 in past the point where the wheel well meets the floor going forward, so there is no floor space ahead of the well. - Driver cabinet 11.5 in deep, passenger 11 in. - Batteries: 10 3/16 × 7 7/8 × 7 1/8 in without terminals, two in parallel, on the shelf over the wheel well, the long way front to back, in a compartment at least 10.5 in tall. Turned across, they are about 1 in too deep for the 11.5 in cabinet. - Above the shelf: two compartments. The front one holds the batteries crossways (7 7/8 in along the cabinet each), 10 mm apart with 15 mm at each end, about 17.5 in in all. The back is cut away behind them (`battWindow`) so they sit into its thickness; a hold down bar across their tops screws to the divider and the end. The rear compartment is about 25 in wide for the electrical panel. - Summer airflow (`airflow`): cool air enters low through slots in the lower panel, rises through shelf slots under both compartments, crosses three high slots in the divider, and leaves through the thermostat fan high on the rear end. The space under the shelf stays empty as the air path. - Each compartment above the shelf has its own door. The default is hinged on the side, opening toward the nearest end of the cabinet. Lift up, drop down and lift off panels are options, and the side hinges can all go left or right as seen from the aisle. Neighbouring doors meet on the centre of the divider, so those hinges are half overlay. Below the shelf stays one lift off panel. Hinge cups, latch holes and the hardware list follow the choice. - Battery shelf: 3/4 in hex ply from stock (enter the measured thickness; 18 mm by default). The compartment shelves use it too. A front rail (pine 1×2 or 1×3, or 3/4 in hex scrap ripped to width) fixes to the shelf front edge with the top flush, and a 1×2 ledger under each end of the shelf screws to the end panel. They are cut by hand, with no CNC parts under the shelf. Pine gets glue and screws; hex scrap gets screws only, since glue does not hold on the film. A 3 in CNC plywood apron is the other choice. Upright posts to the floor are an option (off by default); over the wheel well they stop at the front of the well, which sits 7.5 in deep against the wall. The front edge support can switch to a 1.5 × 1 in aluminium angle or none. - Battery hold down: a cam buckle strap front to back over each battery through slots in the tray and shelf, plus two steel angle brackets that tie the shelf to the van wall. The batteries sit 20 mm off the back so the front slot clears the apron. The battery tray is a locating frame cut from 1/4 in hex on its own sheet (Thin parts, measured 6.35 mm by default); the straps carry the load. - The rear utility plate defaults to 1/4 in hex on the CNC, with aluminium or acrylic on the laser as options. - A Bluetti Elite 200 V2 (13.78 × 9.84 × 12.74 in, Bluetti spec) stands on the floor past the front end for scale. It is not in the parts list or the weight. - No end bay ("Shelf over the well, no end bay"). 2.27 in is left in front of the well, so no component panel goes below the shelf. - The passenger cabinet is Storage until the water plan is settled: two Scepter cans (13.7 in deep) do not fit an 11 in cabinet. - The MultiPlus 2000 does not fit beside the two batteries in a 28 × 44 in cabinet, so it is off by default. The wheel well size is still your earlier 36 × 11 × 7.5 in note. ## Van profile Transit 148 HR, hard coded with sources shown in the page: | Value | Number | Source | |---|---|---| | Interior height | 81.5 in (2,070 mm) | Ford spec | | Max interior width | 70.2 in (1,783 mm) | Ford spec | | Between wheel wells | 54.8 in SRW, 45.4 in DRW | Ford spec | | Cargo length at floor | 143.7 in (3,650 mm) | Ford spec | | Rear door opening | 61.7 × 74.3 in | Ford spec | | Wheel well | 45.5 × 12.5 × 9.5 in | Explorist / Featherbuilt enclosure cutout with clearance. Not a Ford sheet metal size. | | Well centre | 31 in from the rear doors | Your earlier note (13 to 49 in). Measure. | The well can switch to your 36 × 11 × 7.5 in measurement or custom numbers. Every contradiction with the van profile is a warning, never a silent clamp. ## What it does 1. **Two cabinet garage**: driver and passenger cabinets, mirrored, each with a role (Electrical, Water or Storage; swap in one click), placed along the wall or across the van (L shape). Default 57 × 34 × 16 in each. The centre aisle is a first class number with Timber Van Kits presets (41.5, 42.5, 43.5 in), the 54.8 in between wells limit, and a "what fits" readout. 2. **Bed platform and garage height**: clear height 32 to 48 in (default 36), platform thickness, mattress 5, 6 or 8 in, sleeping height and sitting headroom live, with the 36 / 37 / 40 in flags. Fixed, hinged lift up, removable or Bi-Slide style half collapse panels, all nested. LED channel pocketed under one edge. Comparison overlays, including the Murphy / desk 37 in reference. 3. **Electrical**: SOK batteries plus placeholders for MultiPlus 12/2000/80, MultiPlus 12/3000/120, MultiPlus-II 12/3000/120, MPPT 100/50 and 150/60, Orion XS 50, SmartShunt, Lynx Distributor and Cerbo GX MK2. 100 mm clear above and below MPPTs is checked. Inverters get a fire resistant backer part (aluminium or fibre cement) on its own sheet. Vents (laser grille plates or slots) and 12V PC fans (80, 92, 120 or 140 mm, one to four per row, intake low, exhaust high or both) with standard screw hole spacing, printed finger guards and a thermostat switch in the hardware list. Grommet pass throughs, shore power gland, a hinged living side end door with lift off panels on the garage side. Fans work on any cabinet, not only the electrical one. 4. **Water**: two sources. - **Fixed tank**: NW Conversions and S&B envelopes, or a custom envelope, with full and dry weight, an arch notch for the wheel well tanks, a plumbing bay above with pump, accumulator, filter and an Isotemp Slim bay, a sight notch on the face, and pass throughs. - **Jerry cans**: one to three removable cans (Scepter 5 gal military style, Reliance Aqua-Tainer 7 gal, or your size) standing on the floor in an end bay sized for them (default), or on the shelf. The wheel well takes the floor from about 13 to 49 in from the rear doors, so with your measured well 3 floor cans need a 73 in cabinet (bay at the front), 2 need 66 in, and 1 fits the 57 in cabinet behind the well. The default is 2 cans in a 66 in passenger cabinet with the can bay at the front (preset: Two floor jerry cans, 66 in water cabinet). A CNC tray pockets each can, a hold down bar on tool free knobs keeps them in, and each can gets its own draw hose hole and a valve on a manifold, so any number can feed the pump. No water heater, no gray tank; for winter the cans come out and the manifold drains. - A rear utility plate (fill, quick connect, gauge, drain, 12V, USB, 120V) as a laser part; with jerry cans it leaves out the fill, gauge and drain. - **Water ready storage**: a Storage cabinet can be set water ready. It cuts the shelf height, pass throughs and utility plate opening for the water plan now, with a blank cover plate, and draws the water parts dashed and out of the weight until you switch the role to Water. 5. **Centre bay**: FarOutRide tray (19 × 60 in inside, 3 in sides, 15 mm birch, 48 in locking slides) or the Flatline preset; slides derated from the 9308E table, not the 500 lb headline; two DropTop fork mounts staggered; front wheel slot; dirt clean out; L-track; optional Kestrel pattern long drawer above or beside. 6. **Storage and structure**: recessed or surface L-track with 84 in stick count and rings, MOLLE on cabinet ends and the rear doors (White Top Atlas face size), 80/20 frame mode with an extrusion cut list and thin panels, a fold down rear door table with a laser backing plate checked against the tray swing. 7. **Heater**: Espar, Webasto and VELIT placeholders for a bay fit check. 8. **Outputs**: stats bar with aisle, clear height, headroom, dry and full weight, and left / right balance (warns over 100 lb); hardware list with slides, fork mounts, L-track, hinges, latches, gas struts and mounting by L-track, structural rails or rivnuts; every part tagged CNC, Laser, Print, Hand cut or Buy. ## Unverified sizes Placeholders use the sizes in your brief. These are flagged in the page and need checking before cutting: the wheel well (measure it), the tank arch notch (NW does not list it), the accumulator, filter and Isotemp bay, the DropTop size, the 120V cutout, the recessed L-track body and flange, the Accuride 9308E derating numbers, and component weights. ## Known gaps - With the 45.5 in proxy well, a 57 in cabinet with a 13 in end bay has no room for the well: the default preset warns about it on purpose. - With your measured 36 in well (13 to 49 in from the rear doors), a 13 in end bay lands about 1 in on the well at either end. An 11 in end bay toward the rear with a 10 mm backer margin clears everything with no warnings. - Bed sections at 24 in deep take one sheet each. - Not cut or test fit yet. Cut a joint coupon first to set the slot clearance. Status: draft. © Ryan Mitchell — CC BY 4.0.
