CPAP Reservoir Funnel 20mm

thingiverse

This adapter makes it simple to connect a 20mm water reservoir inlet to CPAP machines, allowing for hands-free use so you can focus on holding the water jug while filling becomes effortless. It prints easily without supports and shouldn't require a raft. I used ABS but PLA should work just as well. This design should also print smoothly with other sturdy materials like PETG or TPU.
