Pet Carrier Door Snap-Catch Latch
A snap-catch that bolts on next to the wire door of a hard-shell pet carrier. It replaces a cracked factory latch so you don't have to buy a whole new crate. When the door closes, its wire rides up a ramp and snaps into a 5.5 x 8 mm pocket that holds wire up to about 5 mm thick. The 2.5 mm flex arm is printed on its side, so it bends along the layers rather than across them, and you press the thumb tab to let the door go. The block is 45 x 28 x 16 mm and mounts through the shell with two M4 bolts (4.5 mm holes, 16 mm apart) into captive 7 mm hex-nut pockets.
Raccoon-Proof Bin Lid Snap Latch
A latch that bolts to the outside of a trash or storage bin and holds the lid down. A 3 mm flexing beam with a 10 mm catch tooth snaps over the lid edge, and a pull tab lets a human open it. Two M5 bolts go through a 36 mm wide, 6 mm thick back plate, and each bolt column has three holes (24, 32 and 40 mm up) so you can match the height of your lid rim.
Flexure Snap Latch For Project Box Lids
A screw-on flexure latch for DIY project boxes. A 34 x 24 x 5 mm pad bolts to the box wall with two M3 screws (3.4 mm clearance holes, 20 mm apart). A 2 mm thick, 16 mm wide spring arm ends in a hook with a 3.5 mm catch and a ribbed thumb tab, so the lid snaps shut and lifts off without tools.
Closet Rod Snap-On Belt And Tie Hanger
A belt, tie and scarf hanger with eight upturned hooks. Its C-ring snaps onto a 1-5/16 in (33.3 mm) wood closet rod or a 1 in schedule-40 PVC rod (33.4 mm OD). The 33.8 mm bore has a 31 mm snap mouth so the hanger turns freely on the rod but won't get knocked off. The part is 65 x 167 x 8 mm and prints flat, so belt loads bend the hooks along the layers rather than across them.
PC Chassis Edge Snap Cable Dress Clip
A screwless cable clip that pushes onto any 0.8–2.0 mm sheet-metal edge, like a PC case rail, a server chassis lip or an enclosure cutout. Its tapered wedge slot narrows from 2.2 mm to 0.6 mm and pinches the panel. On top it has three snap-in C-channels with 7.3, 5.3 and 4.3 mm bores, for coax up to about 7 mm, USB/SATA round leads and fan wires. The clip is 42 x 26 x 15 mm and prints flat, so the snap rings and prongs flex in the strong XY plane.
Pi 4 Edge-On DIN Rail Snap Mount
This mount holds a Raspberry Pi 4B or 3B+ edge-on to a standard 35 mm TH35-7.5 DIN rail (1 mm flanges). The board sits on four M2.5 standoffs on the 58 x 49 mm hole pattern and stands at right angles to the rail, so it takes up roughly 25 mm of rail instead of 85 mm. On the 92 x 87 mm plate, a fixed hook grips one rail flange, a flexure latch snaps over the other, and you release it by twisting a flat screwdriver in the slot.
Flagged: mains electrical wiring. Not for safety-critical use without independent engineering review.
RV Bay Door Snap Hold-Open Catch
A two-piece snap catch that holds an RV or trailer storage bay door open in the wind. A 9.6 mm knob on the door stud snaps through an 8.2 mm flexing fork mouth on the wall catch. Both parts are 60 x 20 mm mounting bars with two 4.6 mm holes on 44 mm centres, for #8 wood screws or M4 bolts and nuts. It prints already snapped together.
1/2, 3/4, 1 in Knockout Blank Plug Set
A set of three snap-in blanking plugs for unused electrical knockouts: 1/2 in trade (22.2 mm hole), 3/4 in trade (27.8 mm) and 1 in trade (34.5 mm). They print on one snap-off sprue about 121 mm long. Slotted spring fingers with a 45° barb push in from the front, grip steel box and panel walls about 1–2 mm thick, and leave a flush flange 4 mm wider than the hole on every side.
22 mm Snap-In Step-Down Cable Grommet
A snap-in grommet for a 22 mm hole (the common step-drill size) in a project box, dash or panel wall up to 3 mm thick. It has a 36 mm flange, four barbed spring fingers and a knock-out membrane with score rings at 4, 7, 10 and 13 mm. Trim to the ring that matches your cable and you get a snug pass-through, not a loose hole.
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.
Downspout Elbow Snap-In Wind Clip
This wall clip replaces the factory clip that wind snaps off a folding downspout elbow. Two flexing arms and ramped hooks snap around rectangular "2x3 in" downspout up to 80 mm wide, and a built-in bow spring presses spouts 50–60 mm deep forward against the hooks so they don't rattle. The clip is 130 x 82 x 25 mm and fixes to the wall with two #8 screws through 4.5 mm holes in the side wings. It prints flat without supports, and the arms flex within the layers, so wind load never pulls across the layer lines.
Kitchen Trash Can Bag Rim Lock Clip
A 40 x 20 x 25 mm snap clip that holds a trash bag over the rim of a kitchen bin, so the liner stops slipping down into the can. It prints flat, so its flexible outer leg bends in the strong layer plane. The mouth is 6 mm wide and closes to a 2 mm barb, so it grips rims about 1.5–5 mm thick with the bag film folded over. Ridges on the inner leg bite into the bag, and a thumb tab pries it off.
1-1/4 in Grab Bar Snap-On Towel Hook
A snap-on J-hook that clips onto a standard 1-1/4 in (31.75 mm OD) shower or tub grab bar. It gives you a place to hang a loofah, washcloth or razor strap without drilling tile. The C-clip has a 32.2 mm bore and a 27 mm snap mouth and is printed flat, so the clip flexes in the strong layer plane. The part is 16 mm thick, about 83 mm tall and weighs about 12 cm³.
Snap-On Toilet Bolt Cap And Washer
A replacement toilet closet-bolt cover: a 34.6 mm dome cap, 37 mm tall, that snaps over a 28.8 mm retainer washer. The washer has an 8.5 mm bore for 1/4" and 5/16" closet bolts and sits under the nut. Both pieces print nested as one job, and the four flex fingers let the washer pop out for fitting.
Door Knob Bore Hole Cover Plate
A 79 mm cover plate that hides the abandoned knob hole left in a door after a lockset is moved or swapped for a lever. It has eight flex fingers that snap into a standard 2-1/8 in (54 mm) cross-bore and grip about 53–55 mm. Two countersunk 4 mm holes, 66 mm apart, take #6 wood screws for a permanent fit. It prints face-down, so the visible face is the smooth bed side.
6/8 mm Hood Prop Rod Snap Clip
A replacement retaining clip for a car hood prop rod. It screws flat to the hood inner panel or radiator support with three M4 or #8 screws (4.5 mm holes, 29 mm apart) and has snap-in jaws for 6 mm and 8 mm rods. The bores are 6.3 and 8.3 mm with a mouth 1 mm narrower than the rod and a flared lead-in. The body is 70 x 14 mm and fixes the rattling, loose prop rod you get after the original clip breaks.
2 in Hitch Ball Snap-On Weather Cap
A snap-on cap for a standard 2 in (50.8 mm) trailer hitch ball. It keeps rain, grit and grease off the ball, and off your trouser legs. Six slotted fingers flex over the ball's equator and close to a 47.6 mm lip underneath to hold on. It stands 62 mm tall and is 56.8 mm across. The 45° roof prints without supports and sheds water, and a 5.5 mm lanyard eye on top lets you tie it to the safety chain so it doesn't go missing.
Dual Size EMT Conduit Snap Hanger
A screw-down wall plate with two snap-in saddles that take 3/4 in EMT (23.4 mm OD, 23.7 mm bore) and 1/2 in EMT (17.9 mm OD, 18.2 mm bore), so a conduit and a small pipe or hose run stacked on one anchor point. Overall 102 x 26 x 25.5 mm; two 4.5 mm holes 84 mm apart take M4 or #8 wood screws, the lips wrap past the pipe centreline for a 0.5 mm one-hand snap, and a dovetail tongue and socket on the ends let hangers gang into a continuous run along a wall or joist.
Gas Strut 10 mm Ball Socket End
Replacement snap-on socket end for a gas strut whose plastic cup broke, so a good strut goes back to work instead of in the bin. The slotted cup takes a standard 10 mm ball stud (10.4 mm spherical seat, 9.5 mm snap throat, V-groove for a zip tie or the original wire clip); the 7.2 mm bore self-taps onto the strut's M8x1.25 rod stud with 20 mm of engagement, locked by an M4 set screw through the side. 20 mm barrel with 17 mm wrench flats, 32.5 mm tall — print in PETG if you can.
Snap-In Sink Hole Cover Plug
A snap-in cover plug for the standard 1-3/8 in (34.9 mm) faucet or side-sprayer hole left open in a sink or countertop after a faucet swap. A 50 mm diameter flange hides the hole and six 45 degree ratchet fins on six flexing legs grip deck thicknesses from about 5 mm to 28 mm; overall 50 mm across and 33 mm tall, printed visible-face-down so the show face comes off the plate smooth.
Kayak Deck Paddle Park Clip
A snap-in deck clip that parks a kayak or canoe paddle shaft (30 mm nominal, grips 28–31 mm) against the hull so it stays put while you fish or land — the OEM clip sun-rots and no maker sells it separately. 76 x 30 x 38 mm: 6 mm base plate with two M5 clearance holes at 38 mm spacing for well nuts, plus two 8 x 14 mm lash slots at the ends so it can be strapped to 6 mm deck bungee with no drilling into the hull.
