Oh my days this question againOh my days this guy again <| sep |> Heh , a few people have said so when they ' ve seen mine , but it was easy to printassemble , is surprisingly small , and works really well I have a few issues with pla jamming during dual extrusion because the ao hexagon heatsinks are so short I can ' t cool the idle hotend enough , but abspetgtpu are all happy campers pla works fine for single extrusion , but I think I need pushpull fans to stop heat creep for dual extrusion since I ' m already using the most powerful 25 mm fan could find . Only other annoyance I ' ve really had is the spring tension is fixed the default springs from his kit work great for everything except they ' re not quite strong enough to get a consistent grip on metal filled pla .
