Window Crank Handle Clip Remover Fork
A 165 mm flat fork for removing the hidden spring clip that holds a manual window winder or door handle onto its splined shaft. You slide the 1.6 mm bevelled tip between the handle and the door panel. Its tapered mouth narrows from 16 mm to 7 mm, so it centres on shafts of different sizes and pushes the horseshoe clip off. You don't have to pry, so the 30 mm wide blade only takes load in its own plane. The 26 x 12 mm ribbed grip has an 8 mm hole for hanging it up.

Inverted Oil Bottle Drain-Down Coupler
This tapered double-cone coupler stacks an upside-down quart bottle of oil, coolant or ATF on top of another bottle so the last drops drain from one into the other. The top seat takes bottle necks from about 26 to 50 mm. The 18–30 mm ribbed spigot wedges into necks with an inner diameter of about 19–30 mm. Four ribs inside the seat and three outside the spigot leave air paths so neither bottle seals and glugs. The part is 86 mm tall with a 68 mm drip-lip flange and prints mouth-down without supports.

Split Loom 45° Branch Y Trough
A screw-down Y fitting for split-loom harnesses. A 26 mm main channel takes the trunk run, and a 20 mm branch at 45° takes the wires that split off, so you don't have to tape two looms together at the junction. Under-floor zip-tie grooves let a tie wrap each loom end even after the part is screwed flat, and three 4.5 mm holes take #8 screws. It's 112 mm long and 22 mm tall.

P-Clamp Eight-Spindle Sort Board
A 150 x 100 mm tray with eight 4 mm spindles that hold loose rubber-lined P-clamps by their screw eyes: the back row takes 16, 19, 22 and 25 mm clamps and the front row takes 6, 8, 10 and 13 mm. The back wall has eight U-notches cut to the same sizes. Drop a fuel line, coolant hose or harness into the notches to find its diameter, then take the matching clamp straight off its spindle.

Oil Drain Plug Crush Washer Peg Caddy
A 150 x 70 mm drip-lipped bench caddy for oil changes. It has four 30 mm stacking pegs for M12, M14, M16 and M18 drain plug crush washers, each 0.6 mm under the washer bore so they slide on easily. Notches in front of each peg (1 to 4) mark the size. A 34 mm cup holds the hot drain plug while the oil drains, and the 8 mm rim catches drips.

Long-Reach Transmission Fill Funnel
A 180 mm tall funnel with a 76 mm cup and a 140 mm long spout for topping up transmissions, diffs and power steering through deep, narrow fill holes. The spout is 13 mm OD and narrows to an 11 mm tip around a 7.5 mm bore, so it goes into any fill hole of 14 mm or more. Three standoff ribs hold it off the hole wall so air can get out and the fluid doesn't glug, and a tab with a 6 mm hole lets it hang on a pegboard hook.

Flexure Hose Pinch-Off Clamp M5
This one-piece flexure clamp pinches a coolant, fuel or vacuum hose shut while you swap a hose clamp or a part. The two smooth jaws are 8 x 14 mm and have 88 mm of usable length, enough for hoses up to about 45 mm OD laid flat. One M5 x 40 bolt runs through 5.5 mm holes and threads into a captured M5 hex nut pocket to close the 10 mm jaw gap, and a 2.5 mm living-hinge loop opens the jaws again when you loosen the bolt.

Wiper Arm Washer Hose Clip Set
A snap-off sprue of four replacement clips that hold the washer-fluid hose to a wiper arm. They fit hoses with an outside diameter of 5, 6, 7 or 8 mm. Each clip is 14 x 9 mm and has a flat back. A tunnel 4.8 x 2 mm through the base takes a zip tie up to 4.8 mm wide, so it straps to almost any wiper arm. You don't need the dealer clip that's only sold with the whole arm.

Zip-Tie Top-Post Battery Terminal Boot
A cover for car, marine and mower top-post battery terminals that replaces the missing or cracked rubber boot. The open-bottom hood's inside measures 36 x 52 x 32 mm, so it fits over the post and clamp. A 13 mm U-channel takes battery cables up to about 12 mm OD, and a zip tie through the slot underneath holds the boot to the cable. It keeps tools from shorting the post and slows corrosion. Print it in red for positive and black for negative.

Four-Wheel Lug Nut Rotation Tray
A 172 mm floor tray for tire rotations and wheel swaps. It has four 5-lug rosettes of 26 mm bore, 12 mm deep cups, so each wheel's 19 mm, 21 mm or 13/16 in lug nuts (acorn or flanged) stay together. Raised 1-4 dot markers tell the corners apart, and a 36 mm centre cup holds the wheel-lock key.

Worm-Drive Hose Clamp Standoff Saddle
A screw-down V-saddle that raises a coolant, fuel, vacuum or bilge hose (about 15–40 mm OD) 18 mm off a vibrating firewall or hull. A standard worm-drive band clamp up to 13 mm wide, or a zip tie, passes through a 14 x 3 mm tunnel and wraps over the hose, so the clamp holds the hose in the saddle and never rubs on the panel. The base is 90 x 28 mm with two 5.5 mm holes for M5 or #10 screws.

Spin-On Oil Filter Drain Funnel
A 128 mm funnel for draining used spin-on oil filters. Set the filter upside down on its four stand-off ribs (they fit filters roughly 65–95 mm across) and it drips into a jug through a tapered 20 mm bore spout. The spout's outside ribs leave an air gap in the jug neck so the oil doesn't glug. It prints rim-down with no supports, is 75 mm tall and has a hang tab with a 6 mm hole for a nail on the garage wall.

Snap-Slot Wire Harness Lacing Comb
A 110 x 50 x 10 mm lacing comb for building neat wiring looms. Wires press sideways through V lead-ins and snap into seats, so you never have to thread them from the end: 12 seats on the top edge are 3.2 mm with a 2.2 mm neck at 8 mm pitch (about 18–22 AWG hookup wire), and 8 seats on the bottom edge are 4.6 mm with a 3.2 mm neck at 11 mm pitch (about 14–16 AWG). There is a 60 x 12 mm finger window in the middle, and two M4 clearance holes let you screw it to a harness board or slide it along the bundle while you zip-tie or lace the wires at even spacing.

Brake And Fuel Line Snap Clamp
A snap-in routing clamp for hard lines. It holds two 3/16 in (4.76 mm) brake lines, one 5/16 in (7.94 mm) fuel line and one 3/8 in (9.53 mm) return line side by side, and bolts to a frame rail or firewall with a single M5 or #10 screw through a 5.5 mm hole. It's 73 x 19 x 12 mm and replaces the mismatched bulk P-clips you'd otherwise buy for custom car, ATV and equipment line runs.

Eight-Cylinder Spark Plug Reading Tray
A 128 x 76 mm bench tray for a tune-up. It has eight 15.5 mm wells, 29.6 mm deep, that hold M14 (and smaller M12/M10) spark plugs threads-down, so the plug sits on its hex and the electrode stays off the bench. Raised dots next to each well count 1 to 8 (odd numbers on the front row, even on the back row, matching V8 bank numbering), so every plug stays in cylinder order while you read and gap it.

Blade Fuse Assortment Tray With Puller Trench
A stepped 130 x 80 mm bench or glovebox tray that holds blade fuses upright by amperage. It has 14 mini slots (4.8 x 12.5 mm), 12 ATO/ATC slots (6.2 x 20.8 mm) and 3 maxi slots (9.8 x 30.6 mm), plus an 11 x 72 mm trench that takes the fuse puller. The slots are cut a little oversize compared with the usual fuse bodies (10.9 x 3.6 mm mini, 19.1 x 5.1 mm ATO, 29.2 x 8.5 mm maxi), so the fuses drop in and stand with their heads up for grabbing. Two 4.5 mm holes let you screw it down with #6 or M4 screws inside a van, RV or electronics cabinet.

Trim Clip Hole-Gauge Sort Tray
A 152 x 78 x 30 mm tray with six bays for automotive push-pin trim clips. Each bay has its own test hole in a 2.4 mm ledge that stands in for the panel: 6, 7, 8, 9, 10 and 11 mm, each modelled 0.2 mm oversize. Push a loose or salvaged clip into the holes until it snaps home and you know which bay it goes in and which panel hole it fits. The clip's legs drop into a hidden bridged channel under the ledge, so a clip bought in a mixed variety pack gets sorted by hole size.

Flat-Print Fir-Tree Trim Clip Set
Five breakaway fir-tree trim clips for 6, 7, 8, 9 and 10 mm panel holes. They hold door cards, wheel-well liners, splash shields and bumper trim, and grip panel stacks from about 2.5 to 12 mm thick. Each clip prints flat, so its layer lines run along the pull-out direction, and it has a 24 x 3 mm head and 0.5 mm-oversize barbs that fold on the way in and ratchet against the back of the panel. The row is 136 mm long and 8 mm thick. Snip the 1.2 mm tabs and you have a clip for each common hole size without buying a bag of 20.

Crimp Terminal Gauge Sort Tray
A 148 x 100 x 28 mm tray with 12 bins (34.6 x 30.7 mm each) for sorting crimp terminals. The four columns hold ring, fork/spade, quick-disconnect and butt-splice terminals, and the three rows follow the standard insulation colours: red 22–18 AWG, blue 16–14 AWG, yellow 12–10 AWG. Each row has 1, 2 or 3 dots recessed into the side wall so you can find a gauge at a glance. A 45° ramp at the front of every bin lets you slide a single terminal out with a fingertip.

Brake Line Roller Straightener Block
A five-roller straightening block for 3/16 in (4.76 mm) brake, fuel and copper-nickel line: three 624 bearings on the lower row and two offset above squeeze the tube to a 4.2 mm nip (0.56 mm set) so coiled line pulls through dead straight. 110 x 44 x 18 mm body with V-groove entry and exit guides, 3.4 mm self-tapping holes for M4x16 socket-head screws (the 7 mm head clamps only the bearing's inner race), and four 5.5 mm M5 holes to bolt it to the bench — or grip the 9 mm plate edges in a vise.

Brake Caliper Hanger S-Hook
A flat-printed S-hook that hangs a loose brake caliper from the coil spring, strut body or wheel-well lip so the caliper never dangles on its rubber hose during a pad or rotor job. Both hooks have a 24 mm throat with a 17 mm mouth (takes spring wire up to 17 mm), the body is 136 x 40 x 12 mm with an 8 mm thick hook wall, and a 5.5 mm hole through the spine takes an M5 bolt or a bungee to link two hangers.

Headlight Tab Repair Bracket
A bolt-on repair tab for a headlight housing whose mounting ear snapped off — a 74 x 26 x 5 mm ribbed plate that takes four M4 bolts (4.5 mm clearance, 14 x 14 mm pattern) through the surviving housing flange and gives back a 6.5 mm x 18 mm slotted bolt tab with 16 mm of fore/aft adjustment. A 10 mm registration lip hooks over the housing edge so the bracket cannot rotate while you tighten it, and twin 6 mm ribs carry the bending load between the bolt pattern and the new tab.

Trim Panel And Rivet Clip Tool
A 170 mm no-mar plastic trim tool for automotive interior work: one end is a stepped fork (5.5 mm mouth stepping to 3.4 mm) that slides under push-rivet clip heads and pulls them straight out, the other is a 34 mm wide chisel wedge tapering from 6 mm down to a 1.7 mm edge for popping door cards, headliner trim and sun-visor covers. The underside is dead flat so it spreads prying load on the panel instead of denting it, the fork tip bevels to 1.8 mm to get under flush flanges, and 8 half-round ribs plus a 6 mm lanyard hole make up the handle — plastic so it will not scratch paint, glass or chrome the way a screwdriver does.

Gas Strut Sag Stop Clamp
A split collar that clamps onto the exposed 8 mm chrome shaft of a gas lift support so a tired hatch, hood, toolbox lid or camper door cannot sink shut — an 8.4 mm slip-fit bore, a 28 mm flange that bears flat on the strut's gland, and two M3 pinch bolts with captured M3 nuts (5.7 mm hex pockets). 36 mm tall overall, printed shaft-axis-vertical so the load is compression through the layers, not peel.
