Build steps and tools

Measure what you have
Measure your sheet pans and bannetons, the plywood, the insulation board and the timber, and enter them. Each shelf is the size of one sheet pan, and the number of bannetons per shelf follows from it. Check that the cut list and shopping list fit your sheets and lengths.
Tape measure, square and pencil.
tape measuresquaremarking pencil
Cut the panels
Cut the top, bottom, two sides, back and door from the plywood. Cut the six insulation pieces square and full thickness; score and snap thin board with a knife and straightedge, or saw thick board.
Circular saw or table saw for the plywood, a handsaw if that is what you have; utility knife and ruler for the insulation.
circular sawtable sawhandsawutility kniferuler
Cut the window
For a door with a window, mark the opening on the door, drill a hole inside each corner and cut between the holes with a jigsaw. Cut the larger opening through the door plug with a knife. Sand the cut edges.
Drill/driver and bit for the corner holes, jigsaw, utility knife, sander. Skip this step for a solid door.
drill driverdrill bitjigsawutility knifesander
Build the box and line it
Glue and screw the sides, back, top and bottom together with pilot holes, and check both diagonals before the glue sets. Bore the two cable ports through the right side. Glue in the back, floor, roof and side insulation, cut the port holes through it, and tape every inside joint and the front edge with foil tape.
Drill/driver with pilot and driver bits, clamps, square, hole saw and utility knife.
drill driverdrill bitdriver bitclampsquarehole sawutility knife
Fit the rack
Cut the four uprights and the runners. Screw the uprights through the insulation into the sides, then fix each pair of runners level with each other at the heights in the cut list. Slide a sheet pan in at every level to check it runs freely.
Saw for the timber, drill/driver, square and tape measure.
sawdrill driversquaretape measure
Make the shelves
For slatted shelves, cut the slats and battens, lay the battens so they will sit just inside the runners, and screw each slat down into both. Check each shelf is square and ease every edge. Wire racks need only a test fit. Set your bannetons on one shelf to check the count.
Saw, drill/driver with pilot and driver bits, square and sander.
sawdrill driverdrill bitdriver bitsquaresander
Glaze and hang the door
Glue the insulation plug to the door skin, centred so it clears the lining on every side. Drill the polycarbonate panes oversize at the listed spacing so they can move, and screw one to each face of the door skin over the window. Stick the seal on the plywood front edges, hang the door on its hinges and set the latches so the seal closes evenly all round.
Drill/driver and screwdriver.
drill driverdrill bitscrewdriver
Place the bought parts
Set the heater on the floor and the water pan on the lowest runners above it, the fan high on the back lining, the sensor on the right lining at the middle level and the controller outside on the right. Run the cables through the ports and seal round them. A competent person chooses, wires and checks the heater, fan and controller. Check where condensation collects and that every surface the dough touches is food-safe. This model sets no proofing temperature, humidity or time.
No wiring is designed here.

place components

Place the heater, water pan, fan, sensor and controller in their marked positions; the wiring is done and checked by a competent person

Before you build

Heater, wiring, condensation and food contact are on the builder. A competent person chooses and wires the heater, fan and controller; you check where condensation collects and that every surface the dough touches is food-safe. The model sets no proofing temperature, humidity or time.

Heater, wiring, condensation and food contact are on the builder. A competent person chooses and wires the heater, fan and controller; you check where condensation collects and that every surface the dough touches is food-safe. The model sets no proofing temperature, humidity or time.
Pans, bannetons, water pan, heater, fan, sensor and controller are plain envelopes marking where they go; oval bannetons are drawn as boxes. The window opening and cable ports are cut through the panels; cable paths are listed, not drawn. Screws, hinge leaves, wire rack bars and seal compression are not modelled.
Every size is an original proposal sized from your sheet pans and bannetons; nothing here comes from a tested proofing cabinet.
Shelves are the size of one sheet pan, so every level takes a pan or a shelf. 3 bannetons fit on each shelf, 12 in all.
Heater, fan, sensor and controller are spaces for bought parts. Their products, ratings and wiring are not chosen here, and no proofing temperature, humidity or time is set.
The door seal is drawn at its full 6 mm thickness; how far it compresses depends on the seal you buy.
The window is two polycarbonate panes with the door skin between them as an air gap. Whether they mist up depends on the room and the cabinet; that is not modelled.

What the 3D model leaves out

Pans, bannetons, water pan, heater, fan, sensor and controller are plain envelopes marking where they go; oval bannetons are drawn as boxes. The window opening and cable ports are cut through the panels; cable paths are listed, not drawn. Screws, hinge leaves, wire rack bars and seal compression are not modelled.

Taking the model apart separates parts for inspection; it is not an assembly order.
