Canister intake strainer extension

A 100 mm long slotted strainer that pushes onto your canister filter's 12.80 mm intake tube. The hollow body is a round 45 × 45 mm oval with six rows of 5 mm cuts wrapped all the way around. The total opening is about 30 times the area of the intake bore, so flow won't be choked. A 25 mm socket on top takes the tube until it hits a stop lip. Printed in PLA, it's one piece that stands upright on its flat bottom.

Assembly

  2. Push the strainer onto the intake tube until the tube end touches the stop lip inside.

Good to know

  • I haven't test-fitted the push fit on a real tube. If it's loose or tight, change the Socket fit allowance slider on Adjust (lower is tighter) and print again.
  • PLA is fine at normal tank temperatures but softens at about 55 °C. If your tank runs warm or you want it to last longer, PETG is the safer choice.
  • If your fish or shrimp are small, the 5 mm cuts may let them in. You can make the cuts narrower with the Slot width slider.
