Original Prusa i3 MK3S/MK3S+ to MK3.5S upgrade

<p>If you have an MK3.5 printer, there is no product in our e-shop with the direct upgrade to the MK3.5S. However, purchasing the parts to turn your printer into the MK3.5S separately is possible.</p>
<p>On PrusaSlicer, the MK3.5 and MK3.5S have the same profile.</p>
<p>The parts added will be the new Wi-Fi board and the new NFC board.</p>
<p>You will need:</p>
<ul>
<li>El-box-cover <a href="https://www.printables.com/model/451500-mk4smk39s-printable-parts/files#preview.file.rhr2x">printed </a> or from the <a href="https://www.prusa3d.com/product/el-box-cover-3/">e-shop</a> (1x)</li>
<li>MK4S-Wi-Fi-cover <a href="https://www.printables.com/model/451500-mk4smk39s-printable-parts/files#preview.file.SfE4n">printed </a> or from the <a href="https://www.prusa3d.com/product/wi-fi-cover-3/">e-shop</a> (1x)</li>
<li>M3x12 screw (3x) (a set can be found is the<a href="https://www.prusa3d.com/product/m3x12-black-35-pcs-set/"> e-shop</a>)</li>
<li><a href="https://www.prusa3d.com/product/wi-fi-adapter-2/">ESP-Wi-Fi</a> (1x)</li>
<li><a href="https://www.prusa3d.com/product/nfc-set-2/">NFC set (coil+cable+adhesive film)</a> (1x)</li>
</ul>
<div class="tip-callout">The upgrade is similar to the <a href="http://help.prusa3d.com/guide/5-upgrading-the-connectivity_754320">MK4 to MK4S connectivity update</a>.</div>
<h3>Upgrading</h3>
<h4>Opening the electronics</h4>
<p>To start the upgrade, the printer's electronics need to be accessed. Open the xBuddybox-cover and the El-box-cover. Set them aside as they will be used again later. Remove the Heatbed-cable-holder, the Wifi-cover, and the ESP board. They will not be used anymore.</p>
