PL-259 And BNC Double V-Jaw Coax Wrench
This is a flat 153 mm double-ended wrench with a 60° V-jaw at each end. The large jaw is 28 mm wide at the mouth and wedges round or hex coupling nuts from about 10 to 26 mm, which covers PL-259/SO-239 and N connectors. The small jaw is 16 mm wide and takes about 5–14 mm, for BNC, SMA and F connectors. Because the V grips by wedging, no exact nut size is needed. You can snug and loosen coax at an antenna or radio without crushing the knurl with pliers. It prints flat, 8 mm thick, so the turning load runs along the layers, and it has a 5.5 mm hole for hanging it on a peg.
M3 M4 M5 Rivnut Setting Nut Wrench
This is a 150 x 24 x 12 mm handle for setting rivnuts (threaded inserts for thin sheet metal) with a hardware-store bolt, a hex nut and a washer instead of a $30 setting tool. It has three captive nut sockets: M3 (5.7 mm), M5 (8.2 mm) and M4 (7.2 mm) across flats. Each socket has a clearance bore through the 6 mm floor. To use it, thread the bolt fully into the rivnut and hold the bolt still with a hex key. Then turn the bar so the captive nut drives down onto the washer and collapses the rivnut.
Adjustable M5 Pin Spanner Wrench
This 170 x 24 x 8 mm adjustable pin spanner uses two M5 bolts as pins. One bolt is locked in a fixed hex-nut pocket. The other runs in a 70 mm slot with a captive sliding-nut channel underneath, which sets the pin spacing anywhere from 20 to 90 mm. Use it on two-hole lock rings, threaded caps, pool and spa strainer lids, bike lock rings and lens rings when you don't have a dedicated spanner for that one size. The bar prints flat, so the turning force runs along the layers, and there are notches every 10 mm for repeatable settings.
Print-In-Place Ratcheting 8 mm Hex Nut Wrench
A ratcheting box wrench that prints in one go. It has an 18-tooth sawtooth hub and a flexure pawl built into the handle. The 8.25 mm through-hex fits M5 hex nuts (8 mm across flats) and lets threaded rod pass right through. To reverse the drive direction, flip the wrench over. It is 138 mm long and the head is 46 mm wide. The hub is held top and bottom by 45° bevel races, so it prints without supports.
Graduated Eight-Slot Wrench Wall Rack
A 178 mm screw-on wall rack for combination wrenches. It has eight open-front slots that step from 10 mm to 20.5 mm wide, so the shank drops in and the box end rests on top. A 2 mm front lip keeps each wrench from sliding off. The ledge sits on a 45° wedge, so it prints standing upright with no supports, and it hangs from three 4.6 mm holes that take #8 wood screws or M4 screws.
Garbage Disposal Mount Ring Lug Wrench
A 172 mm lever wrench for turning the twist-lock mounting ring on a kitchen sink disposal. A tapered fork slips over any ring lug or tab from 3 to 10 mm thick, so the tool doesn't depend on any one brand's lug size. A hex pocket in the handle stores the 1/4 in jam-clearing key, and an 8 mm hole lets you hang the wrench under the sink.
P-Trap Slip Nut Toothed Spanner
A flat spanner, 171 x 94 x 10 mm, for turning the plastic slip nuts on P-traps and tailpieces under a sink. Its 60° V-jaw has V-shaped teeth that grip any round or ribbed nut from 40 to 75 mm across, so it covers the common 1-1/4 in and 1-1/2 in drain nuts without rounding them off like channel-locks do. The 8 mm thick handle slides into tight cabinets and has a 7 mm hang hole.
M3 And M4 Nut Holding Reach Wrench
A 130 mm double-ended stick for holding a hex nut behind a panel, inside an enclosure or deep in a robot frame while you drive the bolt from the other side. Each 4.5 mm thin head has a snug hex pocket: 5.6 mm across flats for an M3 nut and 7.1 mm for an M4 nut. A clearance hole (3.4 / 4.5 mm) runs through each head so the bolt tip can pass. A 7 mm thick handle gives you something to grip, and a 5 mm hang hole lets it sit on a pegboard.
Tapered Rib Faucet Aerator Wrench
This is a one-size-fits-most wrench for faucet aerators that are stuck. It has a tapered socket lined with 24 ribs. The opening narrows from 31 mm at the mouth to 16 mm at the floor, so any round aerator shell in that range, from tom-thumb to full-size, seats where it jams and the ribs grip it without stripping the shell the way pliers do. A 140 mm gusseted handle gives the leverage, a 10 mm drain hole in the floor lets water run out, and a 6 mm hang hole is at the end of the handle.
Toilet Tank And Fill-Valve Nut V-Wrench
A 175 mm long, 8 mm thick double-ended V-wrench with serrated 90° jaws. The large end grips plastic fill-valve and flush-valve locknuts and wing nuts from about 40 to 75 mm across. The small end takes tank-bolt wing nuts and supply-line coupling nuts from about 16 to 38 mm. Being plastic, it won't crack porcelain or chew up plastic threads, and you can reach into the tight space under the tank.
