Prusa Bayonet Pattern (now with both parts)

prusaprinters

<p>Pattern for those of you who want to be able to adapt your own spool rollers to a Prusa spool holder bayonet mount. It fits. It works. It doesn't block the other holder on the other side.</p> <p>December 10 update - finished the female component - separate file under downloads on this print.</p> <p>Female part provided as a test piece and the negative that is used to create the test piece. In 3d builder, I used the negative to core out the spool holder arm receptacle hole by positioning the negative inside of the cylinder (test piece) and then using the "subtract" feature, leaving behind the correctly shaped spool holder arm receptacle.</p> <p>This combination of patterns I hope starts to become a sort of universal spool roller/holder arm - I plan on adding new holders and roller adapters to my own smooth spooler. Saves on a lot of plastic by making spool arms and arm receptacles interchangeable across all holder designs (except for those that the spool sits on bearings directly - no arms to adapt in those)</p> <h3>Print instructions</h3><p>Male part - easy to print as a test piece.<br/> Female part - once you stamp the negative pattern into your solid, be sure to manage bridge speed and bridge perimeter detection so you get a good bayonette.</p> <p>The male part is straightforward - just print it and use it as a test piece. Use your favorite design tool to adapt it to your own spool holder shafts.</p> <p>The female part is a negative to be subtracted from any other solid - designed to punch a two sided receptacle that can take two spool arms with the male component at the end. Width of the part to subtract the negative from should be 31.5 mm. Center the female negative in the solid and then subtract the negative, leaving the spool holder arm compatible "positive" bayonet inside of the solid.</p>
