MMU2S Selector with spring loaded FINDA ball

prusaprinters

<p>I wanted to experiment with alternative mountings of the MMU, so I incoorperated a spring to the FINDA ball to exclude the gravity factor.</p><p>Knife- and tube-fittting holder is slightly modded, and I added the FINDA cable guide. These mods are not nessesary.</p><p>Opening to filament canal and FINDA-ball were inspired by emanuvele, darBis, daniel_karlsson among others.</p><p>PETG, standard settings, no supports, I used 0,15mm layer, but 0,2 mm is ok.</p><p>I had no spring wire so I made the spring of a guitar D-string. My prototype was a paper-clip which worked, but prefereably use some kind of spring steel with diameter between 0,6 to 1,0 mm.</p>
