Eheim filter intake pipe suction cup clip replacement
A replacement clip that holds the intake and outflow pipes of an Eheim Classic or Professionel canister filter against the aquarium glass when the original clip splits and the pipe starts floating free. The clip is a 16.4 mm C-ring for the 16 mm intake pipe used with 12/16 hose, with a 2 mm wall and a 14 mm mouth that snaps over the pipe, joined to a 6 mm stud with a 1 mm groove that accepts a standard 30 mm suction cup. Print it lying flat in PETG, which stays flexible in water and does not leach; avoid PLA, which softens and goes brittle in a warm tank.
Eheim, Fluval and Oase pipes come in 12, 16 and 19 mm, and suction cup stems vary, so a clip generated to your pipe holds firmly. In SpeakCAD you give the pipe and stem diameters, preview the clip in the browser at no cost, ask for a double clip for two pipes in the chat and download the STL.
Model an aquarium pipe clip with a 16.4 mm inner diameter C-ring, 2 mm wall, 12 mm wide and a 14 mm mouth for an Eheim 16 mm intake pipe, joined by a 6 mm neck to a 6 mm suction cup stud 8 mm long with a 1 mm retaining groove and 0.5 mm fillets.
