3/4" threaded adapter for Straight Line boat ballast bags

thingiverse

I have a wakeboard boat equipped with a couple of standalone ballast bags and a generic pump featuring a 3/4" male threaded fitting on the end (see photos). A friend surprised me with a Straight Line ballast bag but didn't realize it necessitated an entire different water pump to fill the bag. We were unable to locate a vendor that sold adapters allowing us to connect my pump to his bag, so 3D printing came to the rescue. This part fits flawlessly and gets the job done. I did experience some minor leaking while filling the bag, but it could probably be resolved by attaching a small piece of rubber to the end of the component. I'm uploading the part in the hopes that it can help someone else avoid similar difficulties. I suggest printing this part with heat-treated PLA so that it withstands summer heat. I used Proto Pasta. ABS may also work, but I haven't utilized it since I lack a heated bed. Print the part with supports and 100% infill for added strength.
