3-1/2 in Deck Baluster Spacing Gauge
This is a hook-on spacer block for building deck railings. It is exactly 89 mm (3-1/2 in) wide, so every gap comes out the same and stays under the common 4 in sphere rule. The 25 mm lip hooks over the top of the rail, so the block hangs between face-mounted balusters while you screw the next one in. It is a ribbed open frame (89 x 110 x 20 mm body) with a finger hole for pulling it back out.
2x2 Deck Baluster Repair Shoe
A screw-down socket shoe that re-secures a loose or rot-damaged 2x2 wood deck baluster (1-1/2 in = 38 mm square) to the top of a 2x4 bottom rail or tread without tearing out the railing section. It has a 39 mm square cup 22 mm deep, drain notches so water can't pool, #6 cross-screw holes (4.0 mm) through both wall pairs, and a 92 x 47 mm gusseted flange with four counterbored 4.8 mm holes for #8 or #10 deck screws.
Spine Deck Pi 4 Plate
A 170 x 100 x 4 mm ribbed electronics deck for a rover chassis. It has raised bosses on the 58 x 49 mm Raspberry Pi 4 pattern with M2.5 nut pockets underneath, four 5.5 mm M5 holes for bolting to rails, slots for a PCA9685 servo board, battery-strap slots and wire pass-throughs.
Motor-Clearance Deck Leg
A tapered, hollow 60 mm leg/standoff that lifts a robot deck or chassis plate high enough to clear gearmotors and wiring underneath. It has a 32 mm square foot and a 20 mm square top pad with a 4.0 mm bore for an M3 brass heat-set insert, and the walls are 2 mm thick to keep material use low.
Pi 4 Rover Deck With Legs
A 120 x 90 x 3 mm raised electronics deck with four integral 10 mm legs, part of the 'N20 4WD Skid-Steer Rover Base' kit. The legs stand it 40 mm above the chassis plate, and each foot takes an M3 heat-set insert (4.0 x 6 mm bore) for M3x8 screws from under the chassis. The deck has 2.9 mm M2.5 holes on the Raspberry Pi 4 58 x 49 mm pattern with 6 mm x 3 mm spacer bosses, a 4 x 7 grid of 3.4 mm M3 holes on a 10 mm pitch for a motor driver or ESP32, and two 30 x 10 mm cable windows.
18650 Battery Top Deck
Part of the 'NEMA17 Self-Balancing Robot Frame' kit (print ×1): the 120 × 80 × 4 mm top deck, which bolts to the stack columns with four M3x10 screws through 3.4 mm holes at (±44, ±34). A tray with 2 mm walls rises 14 mm above the deck and holds a 3S 18650 pack in a 70 × 58 mm space. Four 20 × 3 mm slots take two 20 mm hook-and-loop straps. A 12 × 8 mm notch in the end wall and a 20 × 8 mm floor slot route the battery leads down to the electronics deck.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
EMT String Light Mast Bracket
A two-saddle wall bracket that carries a 3/4" EMT conduit mast (23.4 mm OD, 23.7 mm slip bore) flat against a deck post, 4x4 or fence rail for hanging café/string lights. 148 x 50 x 42 mm plate with six 5.5 mm holes for #10 wood screws (4.8 mm shank) or M5 bolts, saddle centres 104 mm apart, and an M5 pinch bolt with a captive 8 mm hex-nut pocket in the upper ear to lock the mast against sliding or spinning; the 18 mm throat is narrower than the conduit so the mast is threaded down through both cradles and stays captured.
