US garden hose to BSP 0.75 sprinkler adapter

prusaprinters

<p>The female thread works with a US garden hose (0.75 11.5NH seems to work well). &nbsp;The male thread is BSP 0.75, which I guess is used on some sprinklers in the UK and/or EU?</p><p>TBH I'm not entirely sure if this is useful for any more than one particular sprinker model, so I'm posting this as a remix of that model in case it's really only useful for that model. &nbsp;It <i>may</i> be useful for other stuff, but YMMV.</p><p>The .f3d is included in case you want to make the inlet or outlet longer or shorter.</p><p>I recommend printing at 0.15mm layer height so the threads have a better chance of working.</p><p>The intended printing direction is the small end down, so that the interior of the bigger inlet end can have a flat surface for a washer (if desired).</p><p>This seems to work well enough without a washer for a sprinker, since a little bit of a leak isn't necessarily a big deal for a sprinkler. &nbsp;For use as a coupler (assuming BSP 0.75 hoses are even a thing), presumably a washer would reduce leaking.</p><p>The only potentially interesting thing about the model itself is how the outlet thread transition to the sorta-conical portion works - it starts at the exact profile of the upper part of the outlet threads, so the sorta-conical portion isn't perfectly conical etc. &nbsp;This is intentional to help it print properly outlet-end (BSP-end) down while preserving full strength.</p><p>The BSP threads seem to work ok with 3D printed BSP threads, though in that usage they can be a little tight. &nbsp;A wrench can be used on the adapter if printed from PETG and you're careful not to squish it too hard. &nbsp;The US garden hose inlet end works with the one garden hose I've tried so far (without a washer, so far).</p><p>&nbsp;</p>
