This is a printable pool vacuum cleaning nozzle designed to fit INTEX 1 1/4" filter pump hose. It also fits standard broomstick pole. http://youtu.be/FkS9bqbzDso It is designed to allow cleaning of the small 8-12' INTEX/Bestway pools via filter pump rather than Venturi type vacuum. EDIT: Version v2 added. Modified design has improved bevel angle to allow more natural nozzle to ground parallel position. I have only tested (printed and used) old design therefore v2 nozzle is not shown on pictures or video. Pros: Cons: Tested on MB 2x using ABS at 0.3mm with 30% infill, enabled raft and no supports. NB. Let me know if you would like a different nozzle angle or any other size modification.Tested on MB 2x using ABS at 0.3mm with 30% infill, enabled raft and no supports.
