    The bottle opener is a low-cost, 3D-printed handheld tool that assists people with arthritis, limited finger dexterity or other disabilities to open standard water bottle caps (⌀ 30mm or 1.18”). This 3D Printed Assistive Device provides a large gripping surface and clamps onto the caps of standard water bottles with a small squeeze, allowing users to remove or screw on water bottle caps.

    Edit 2021-June-30: Updated print time from 2.5 to 4 hours.


    Article mentioned a 1.5h print time, what settings are you using ? On an Ender 3 with 4 walls, 50% infill, .4mm nozzle, .2mm layer height at 50 mm/s is 4 hrs, 70 mm/s is 3 1/2. Am I missing something ?



    Hey @marchache1717 – to which article are you referring? I’ve updated the listing here to provide a more realistic print time (from 2.5 hours to 4 hours). I suspect that figure may have been based on the default infill, not 50%.

    Just wanted to make sure I wasn’t missing anything to make it faster. Have had a couple of requests for one.

    What’s the durability like?
