M3 Screw-Ear Small Tubing Clamp Trio
A set of three split-ring clamps for small tubing, with 6.5, 9 and 11 mm bores, joined on a snap-off sprue bar. Each one closes with an M3 bolt through a 3.4 mm clearance hole into a captured M3 nut pocket (5.7 mm across flats), so you can squeeze silicone, vinyl or air-line tubing tight onto barbs without hunting for tiny worm-drive clips.
Print-In-Place Thumb Roller Tube Clamp
This is a print-in-place roller clamp, like the ones on IV lines, for soft vinyl or silicone tubing from 4 to 10 mm OD. It works on aquarium, drip-irrigation and homebrew siphon lines. A 20 mm knurled thumb wheel rides on 5 mm axle stubs in grooves cut into the side walls of a 60 x 22 x 34 mm body. Rolling it along a 13° sloped roof narrows the gap from 10.5 mm (fully open) to 0.8 mm (pinched shut), so it throttles flow smoothly anywhere along that range.
Aquarium Rim Clamp Hose Saddle
A screw-adjustable clamp that hooks over an aquarium rim or bare glass up to 18 mm thick and carries a 90° saddle trough for a filter hose, heater cord, CO2 line or probe cable, with a 3.5 x 8 mm zip-tie slot under the trough to lock the line down. Overall 64 x 37 x 25 mm; tightens with an M4 x 30 screw into an M4 heat-set insert (5.5 mm bore) in the outer jaw, so it fits rimless tanks, trimmed tanks and sump baffles without a single guessed dimension.
Sump Rim Probe And Tube Rack
A clamp-on rack that hangs over an aquarium sump wall or baffle up to 20 mm thick and organises two 10–13 mm probe bodies (pH/ORP/temperature) in snap-in C-clips plus two 4 mm OD dosing lines in 4.3 mm vertical guides, all held over the water instead of dangling. 48 mm saddle spans the rim, 58 mm long, 32 mm legs; an M4 heat-set insert (5.5 mm bore) takes a 25–30 mm M4 thumbscrew that clamps it to any glass thickness.
