Wind-Lock 4x4 Vinyl Fence Post Cap
A flat replacement cap for 4 in (101.6 mm) vinyl/PVC fence posts, for when the original has gone brittle or blown off and the post size or colour is no longer sold. Eight angled flex fins in a 104 mm skirt grip posts from about 100 to 103.5 mm. A slotted 4.5 mm hole in each side lets you fix it with #8 (4.2 mm) screws so it stays on in wind. The cap is 116 mm square with a 3 mm drip lip.
Resin Shed Door Slotted Replacement Hinge
A 96 mm print-in-place butt hinge to replace broken plastic hinges on resin garden sheds and storage boxes. Each 44 mm leaf has two 5.5 x 12 mm slotted holes so it fits existing screw positions, plus a round 5.5 mm centre hole for an M5 bolt or #10 screw. The 14 mm knuckles turn on a fused 6 mm pin with 0.5 mm clearance, so it prints assembled with no supports.
Notched RV Roof Vent Prop Stay
A replacement prop arm for manual caravan/RV roof vents and hatch lids. It's a 168 mm long, 18 mm wide, 7 mm thick bar with a bossed 5.5 mm M5 pivot hole at one end. At the other end is a 90 mm slot with six notches 16 mm apart, so the stud on the lid can rest at six different opening heights. The slot lets it fit lids whose stud sits anywhere along that range, so you don't need the discontinued dealer part.
Pinch-Clamp RV Dump Valve T-Handle
A replacement T-handle for RV black and grey tank dump valves with an 8 mm stem. It clamps onto the stem with one M4 pinch bolt and a captured M4 nut, so you don't need a pin or set screw. The 110 x 58 x 16 mm grip lies flat on the printer bed so the pulling force runs along the layers, and it has finger scallops and lanyard slots. The 8.3 mm bore is 17 mm deep, with a 4 mm solid entry collar ahead of the split jaw.
Set-Screw Patio Umbrella Rib Tip Cap
This is a replacement end tip for a patio umbrella rib. The rib slides into a 9 x 6.4 mm socket that is 26 mm deep, which takes steel U-channel ribs up to about 8.5 x 6 mm or round fibreglass ribs up to 6 mm. Two M3 set screws, self-tapped into raised bosses, clamp the tip to the rib. A 6 mm neck and an 11 mm knob hold the canopy's corner pocket, so the fabric stops tearing on a bare rib end. The tip prints lying flat, about 55 mm long, so canopy tension runs along the layer lines.
Cornhole Folding Leg Pivot Bracket
This bracket replaces the stamped-steel folding-leg hinge on a cornhole board, which tends to bend or rust. It screws to the inside of a 2x4 frame rail (89 mm tall) with four countersunk #8 wood screws through 4.6 mm holes. It has an 8.3 mm pivot bore for an M8 or 5/16 in carriage bolt, a raised 3 mm washer boss for the leg to turn on, and a gusseted stop wall. The stop face sits 45.5 mm from the pivot so a 3.5 in (89 mm) 2x4 leg stops square to the rail. The plate is 102 x 85 x 6 mm; print it in PETG or ASA for outdoor use.
Greenhouse Vent Opener Slotted Arm
A replacement for the plastic link arm that snaps on wax-cylinder greenhouse and cold-frame vent openers. It is a ribbed 169 mm strap. One end has a 5.5 mm M5 eye with a captive hex-nut pocket. The other end has a 35 mm adjustment slot, so it bolts to the existing lid bracket at any length and no exact OEM hole spacing is needed.
Screw-On Cooler Lid Snap Latch Set
A screw-on replacement for a snapped Igloo or Coleman-style cooler latch. A 40 x 16 x 10 mm lid pad holds a 24 mm wide, 3 mm thick flex arm that drops 58 mm down the cooler wall. Its 4.5 mm ramp tooth snaps under a separate 36 x 16 x 6 mm keeper plate. Both pieces take #8 wood screws: the pad has 4.6 mm slots with 6 mm of height adjustment, and the keeper has counterbored 4.6 mm holes. They print together on breakaway tabs, so a cooler with a good body but a broken latch can be put back in use.
Boat Trailer 2x4 Bunk End Cap
A cap that slides over the rear end of a carpeted 2x4 boat-trailer bunk, so the hull slides onto a smooth chamfered nose instead of catching on frayed carpet and the cut lumber end. The pocket is 100 x 49 x 36 mm. Crush ribs grip a 38 x 89 mm board wrapped in roughly 4–5.5 mm of carpet, and there are three drain slots so water doesn't sit against the wood. Fix it with #8 pan-head screws through four 4.6 mm side holes, none of which face the hull.
Flex-Rib Truck Bed Stake Pocket Cap
A push-in cap for the rectangular stake pockets on pickup bed rails. Instead of matching one OEM size, eight 1.2 mm flex ribs grip any pocket from about 34 x 30 mm up to 41 x 37 mm, so measure yours before ordering. The 60 x 54 mm flange keeps rain and debris out of the pocket, and a pry notch on the underside lets you lever the cap out with a flat screwdriver.
Twin-608 Compost Tumbler Drum Roller
A replacement drum roller for barrel-style compost tumblers. It has a 60 mm OD tread, is 32 mm wide, and has a 72 mm guide flange that keeps the drum from walking off the roller. Two press-fit 608 bearings (22 mm OD) ride on an 8 mm rod or M8 bolt axle, so it replaces plastic rollers that wear flat or crack. It is built with spokes and a drained web, so no solid slab soaks up water or compost.
Bolt-Clamp Basketball Rim Net Hook
A clamp-on replacement net hook for basketball hoops like Lifetime whose original hooks have broken off. It has a 20 mm V-bottom U-saddle that fits round rim stock from about 14 to 19 mm, and one M4 cross-bolt with a captive nut pulls the arms in to clamp the rim. A 5 mm J-slot below holds the net loop. The part is 30 x 61 x 12 mm and prints flat, so the net's downward pull runs along the layers, not across them.
Patio Umbrella Folding Crank Handle
A replacement crank for patio umbrellas (Hampton Bay-style market umbrellas) whose handle has snapped. It has a split collar with an 8.3 mm bore, closed by an M4 bolt into a captured nut, that clamps 7.5–8.3 mm round or D-flat spool shafts. The folding grip on the end is print-in-place. The crank radius is 70 mm, the part is 152 mm long overall, and the grip folds flat in line with the arm when you're not winding. It prints collar-upright, so the clamp and winding torque both stay in the layer plane.
Snowblower Sled-Runner Skid Shoe
A replacement skid shoe for a snowblower auger housing. It has a 130 mm sled runner, 22 mm wide and 7 mm thick, that turns up at both ends so it glides over gravel and pavement cracks instead of digging in. The two vertical adjustment slots are 9 mm wide, fit 5/16 in or M8 bolts, sit 70 mm apart by default and give 21 mm of height travel. Measure your old shoe's hole spacing and set BOLT_SPACING to match it.
Wheelbarrow Tub Support Wedge Block
A replacement for the plastic wedge that sits between a wheelbarrow tub and its handle rail. It is 90 x 40 mm and tapers from 18 to 38 mm tall (a 12.5° pitch). Underneath is a 26 mm wide 90° V-saddle that seats on round steel handle tubes about 25–40 mm across or on the edges of a wooden rail. The through-slot is 6.8 x 20.8 mm, so a 1/4 in or M6 tub bolt lines up even when the original hole spacing varies. The ribbed top has open pockets to save material.
