Designed as low cost reusable alternative to the expensive commercial single use cannisters. Cheap and easy enough to have several on hand, and has worked well for us for years.
I print the parts separately in PETG with a 0.6mm nozzle with variable layer height, 6 perimeters, and 6 top and bottom layers. Print one of each for a complete unit.
The Collar part CA/superglues to the top of the lid to mount the filter that blocks liquid from getting sucked into the pump. The O-ring fits around the inside core of the lid to form a compression seal when closed.
The ball is captive in the central cylinder, and floats up to block the suction when the cannister is full. It can be fully disassembled for cleaning by unscrewing the cap and removing the ball.
Suctioned fluids enter through the tubing attached to the barbed fitting below the level of the diamond openings where the suction draws from. It can be quite full before clogging up the filter cartridge (designed to swell closed when wet to protect the pump). It is resistant to clogging with tipping due to the indirect air path through the core.
This thing can take some abuse carried around in a bag every day, but the connection to the suction pump with silicone tubing jammed in is a bit janky and could stand some improvement.
Requires:
Recommended: in-line hydrophobic filter for suction machine (consumable)
Search the names on Google or Amazon, listings change so frequently that links would be pointless.
