MMU1 Cooling Tower

prusaprinters

<p>MY MMU1 extruder motors where running a bit hot on long prints so I designed this for them.</p> <p>PLEASE DO NOT attempt to wire up the fans or switch box unless you know how to, If you don't get someone to help you that does.</p> <p>The Switch box is completely optional you can wire it in anyway you want to and use any 40x40x10 fan as well.</p> <p>You will need 2x 40x40x10 12V fans<br/> I used this fan which comes with mounting screws:<br/> <a href="https://www.amazon.com/dp/B009NQLT0M/ref=cm_sw_r_tw_dp_U_x_Q37jDbM4TNNN7">https://www.amazon.com/dp/B009NQLT0M/ref=cm_sw_r_tw_dp_U_x_Q37jDbM4TNNN7</a></p> <p>As for how to wire the fans up you can use the optional<br/> "Switch box" that I used in the pictures or just connect them as you like.</p> <p>These are the parts I used on the switch box</p> <p>LED Light:<br/> <a href="https://www.amazon.com/dp/B074SH8GTK/ref=cm_sw_r_tw_dp_U_x_ed8jDbMF1XKPA">https://www.amazon.com/dp/B074SH8GTK/ref=cm_sw_r_tw_dp_U_x_ed8jDbMF1XKPA</a></p> <p>Switch:<br/> <a href="https://www.amazon.com/dp/B071Y7SMVQ/ref=cm_sw_r_tw_dp_U_x_M37jDb53RS27T">https://www.amazon.com/dp/B071Y7SMVQ/ref=cm_sw_r_tw_dp_U_x_M37jDb53RS27T</a></p> <p>Male DC connector:<br/> <a href="https://www.amazon.com/dp/B073W4V9VB/ref=cm_sw_r_tw_dp_U_x_S37jDb8PYWZE7">https://www.amazon.com/dp/B073W4V9VB/ref=cm_sw_r_tw_dp_U_x_S37jDb8PYWZE7</a></p> <p>DC power supply:<br/> <a href="https://www.amazon.com/dp/B00Q2E5IXW/ref=cm_sw_r_tw_dp_U_x_J37jDb9VGBTMJ">https://www.amazon.com/dp/B00Q2E5IXW/ref=cm_sw_r_tw_dp_U_x_J37jDb9VGBTMJ</a></p> <h3>Print instructions</h3><p>You will need to print 2x of the Cooling towers and I included the files as .amf which will work for both MMU and single mode.</p> <p>You will need supports on the "Switch box".<br/> Support blockers are included in Switch box .amf file because only a few areas need them.<br/> Print at 0.20mm resolution.</p> <p>Switch box lid doesn't need supports but prints better at<br/> 0.15mm or 0.10mm resolution.</p>
