prusaprinters

<p>Here is my Spool Holder and handle system for my Ender 3 v2 and other 2020 extrusion based printers. This system optimized for direct drive systems. You can safely use dual Z with belt like me. I designed it pretty solid I may even be exaggerating a little.:)</p><p>The main influence of this system was <a href="https://www.thingiverse.com/thing:2119644">SPANNERHANDS Spool System</a> by <a href="https://www.thingiverse.com/3dmasterrace/designs">3DMasterRace</a> and <a href="https://www.thingiverse.com/thing:4712122">Fillament spool holder</a> by exiof. Note: I cant find Spannerhands Spool System on Printables.com.
